Description

Technical Field

[0001] This utility model relates to the field of SMT equipment technology, and in particular to a receiving module. Background Technology

[0002] In the surface mount technology (SMT) production process, the continuous and stable supply of material tape, as the core carrier of electronic components, directly determines the production efficiency and product yield of the mounting equipment. To avoid production line downtime caused by the depletion of a single material tray, the material receiving machine has emerged. Its core function is to precisely connect the nearly exhausted material tape on the old tray (hereinafter referred to as "old material tape") to the material tape on the new tray (hereinafter referred to as "new material tape"), achieving seamless material tape supply, significantly reducing equipment downtime, and improving overall production continuity.

[0003] During the operation of the receiving machine, a tail section camera module is typically configured to ensure that the subsequent cutting process can accurately remove blank areas without components from the old material strip. The core function of this module is to accurately locate blank areas on the old material strip using visual recognition technology, providing precise position signals to the cutting mechanism and preventing damage to usable components due to cutting deviations or leaving blank sections that could affect subsequent mounting. To achieve stable conveying of the material strip on the track, a cover plate is installed above the tail section conveying track of the receiving machine. This cover plate effectively restricts the vertical movement of the material strip during conveying, preventing the material strip from deviating from the preset conveying path due to vibration, offset, or other issues, thus ensuring conveying stability.

[0004] However, since the tail material camera module needs to directly acquire a clear image of the material strip on the track for identification, the existing technology involves creating an opening in the cover plate corresponding to the identification area of ​​the tail material camera module, allowing the tail material camera module to directly photograph the material strip on the track through this opening. But this opening design has a significant drawback: during the conveying process, the material strip is not kept flat, and the material strip is very prone to jamming at the opening.

[0005] Material jamming not only interrupts the receiving process of the receiving machine, affecting the normal operation of the production line, but can also cause damage to the conveyor belt, component detachment or damage, and increase production costs. Furthermore, operators need to frequently stop the machine to troubleshoot and resolve jamming issues, which not only reduces production efficiency but also increases the complexity and labor intensity of manual operations. Therefore, how to improve the structure of the existing receiving machine cover to effectively avoid material jamming at the opening of the identification area has become a pressing technical problem to be solved in the current SMT equipment industry. Utility Model Content

[0006] The main purpose of this utility model is to propose a material receiving module, which aims to solve the problem of material jamming at the position where the cover plate identifies and distinguishes the tail material.

[0007] To achieve the above objectives, the present invention proposes a material receiving module, comprising a mounting base, a tail material buffer device, a fixing plate, a cover plate, and a tail material camera module. The tail material buffer device is connected to the mounting base and is used to store tail material.

The cover plate is placed on the fixing plate to cover the upper part of the track groove, and the cover plate is made of transparent material. The tail material camera module is connected to the mounting base and located above the cover plate for acquiring images of the material belt located on the track groove.

[0008] In one embodiment, the cover plate is made of quartz glass, PMMA, or PC.

[0009] In one embodiment, the front end of the cover plate facing the track groove has a guide slope.

[0010] In one embodiment, the upper end of the tail material buffer device has an opening, which is strip-shaped, and the width of the track groove is equal to the width of the opening.

[0011] In one embodiment, the receiving module further includes a light-blocking box, which is mounted on the fixing plate and located above the track groove.

[0012] In one embodiment, the cover plate extends from the end of the opening to the end of the track groove.

[0013] In one embodiment, the receiving module further includes a first light source located below the track groove and positioned directly opposite the light-blocking box.

[0014] In one embodiment, the receiving module further includes a bracket, which is mounted on the mounting base, and the tailing camera module is mounted on the bracket.

[0030] This utility model proposes a material receiving module.

[0031] Please see Figures 1 to 5 In one embodiment of this utility model, the receiving module includes a mounting base 10, a tail material buffer device 20, a fixing plate 30, a cover plate 40, and a tail material camera module 50. The tail material buffer device 20 is connected to the mounting base 10 and is used to store tail material. The fixing plate 30 is mounted on the upper end of the tail material buffer device 20, and a track groove 31 is formed on the fixing plate 30 for feeding the material belt. The cover plate 40 is placed on the fixing plate 30 to cover the upper part of the track groove 31; the cover plate 40 is made of transparent material. The tail material camera module 50 is connected to the mounting base 10 and located above the cover plate 40, and is used to acquire images of the material belt located on the track groove 31.

[0032] Specifically, the mounting base 10, as the basic load-bearing component of the receiving module, serves as the assembly benchmark for the entire equipment. It provides stable installation support for other functional modules, ensuring that each component maintains relative positional stability during operation. This is fundamental to achieving the overall structural integrity and operational stability of the receiving module. The tail material buffer device 20 is fixedly installed at one end of the mounting base 10, providing accommodating space or a conveying channel. Its core function is to temporarily store the tail material (old material strip) on the old material tray that is about to be received. Through buffering, it regulates the tail material conveying rhythm, preventing interruption or accumulation of tail material supply, and providing continuous and orderly material strip input for subsequent strip identification, cutting, and connection processes. The fixing plate 30 is fixedly installed on the upper end of the tail material buffer device 20, connecting with the discharge end of the tail material buffer device 20. The upper surface of the fixing plate 30 has a track groove 31 extending along the conveying direction of the material strip. The size of the track groove 31 is adapted to the width and thickness of the material strip, guiding and limiting the material strip to ensure accurate passage along the preset path. The cover plate 40 is made of transparent material and is placed on the upper surface of the fixing plate 30, completely covering the upper area of ​​the track groove 31. The transparent material does not obstruct the view, and at the same time, in cooperation with the fixing plate 30, it forms a relatively closed conveying space in the track groove 31, restricting the up and down movement of the material belt during the conveying process and preventing the material belt from leaving the track groove 31 due to vibration, external interference, etc.

[0033] The tail material camera module 50 is connected to the mounting base 10, and its mounting position is directly above the cover plate 40, with the lens facing the cover plate 40 and the track groove 31 below it. The tail material camera can move relative to the track groove 31, moving to directly above the recognition area. The tail material camera module 50 can capture real-time images of the material strip in the track groove 31, providing visual data support for subsequent recognition of blank areas of the material strip and positioning of the cutting position.

[0034] In this embodiment, the tail material camera module 50 is located above the cover plate 40. Combined with the light-transmitting characteristics of the transparent cover plate 40, it can directly and clearly acquire images of the material strip within the track groove 31 without needing to create an opening 21 in the cover plate 40. This ensures the image clarity required for recognition while eliminating the risk of material jamming caused by the opening 21, providing high-quality visual data for subsequent blank area recognition and precise cutting. Therefore, it avoids material jamming caused by the opening 21, ensuring the normal operation of the production line, improving production efficiency, and reducing the increased complexity of manual operations and labor costs due to the opening 21.

[0035] Furthermore, the cover plate 40 is made of quartz glass.

[0036] Specifically, quartz glass, as a special transparent inorganic non-metallic material, possesses inherent properties such as high light transmittance (especially in the visible and near-infrared light bands, where the light transmittance can reach over 90%), excellent physical stability (high temperature resistance and strong resistance to thermal shock), good mechanical strength (high surface hardness, not easy to be scratched or deformed), and chemical inertness (not easy to react with material strips, components, or impurities in the environment). It is different from ordinary transparent plastics (such as acrylic and polycarbonate) and is more suitable for the operating scenarios of material receiving modules in terms of performance.

[0037] Leveraging its high light transmittance, the quartz glass cover 40 allows the tail material camera module 50 to accurately capture the detailed features of the material strip within the track groove 31, unaffected by material light loss. Especially when identifying blank areas of old material strips, it more clearly distinguishes the boundary between blank sections and valid component sections, reducing cutting position deviations caused by image blurring, lowering the risk of incorrect cutting, and further ensuring material receiving quality. The high surface hardness of quartz glass (Mohs hardness approximately 7, higher than ordinary plastics) makes it less prone to burrs and scratches, and its strong dimensional stability prevents deformation over long-term use. This avoids material strip snagging and squeezing problems caused by uneven or deformed edges of the cover 40. Simultaneously, its smooth surface reduces frictional resistance during material strip transport, lowering the probability of material strip jamming within the track groove 31. Compared to ordinary plastic cover 40, this further optimizes the jamming prevention effect.

[0038] It should be noted that the cover can also be made of other transparent materials, such as PMMA or PC.

[0039] Furthermore, the front end of the cover plate 40 facing the track groove 31 has a guide slope 41.

[0040] Specifically, the guide ramp 41 is positioned at the feed end of the track trough 31. When the cover plate 40 is closed on the fixed plate 30, the guide ramp 41 is directly above the inlet of the track trough 31, and its inclination direction is completely consistent with the conveying direction of the material belt entering the track trough 31, forming a smooth guiding path from the discharge end of the tail material buffer device 20 to the interior of the track trough 31, thus working in conjunction with the guiding function of the track trough 31. The guide ramp 41 solves the problem of inlet obstruction when the material belt enters the track trough 31. Through a smooth transition structure, the guide ramp 41 guides the material belt into the track trough 31, eliminating the risk of jamming at the inlet of the track trough 31.

[0041] Furthermore, the upper end of the tail material buffer device 20 has an opening 21, which is strip-shaped, and the width of the track groove 31 is equal to the width of the opening 21.

[0042] Specifically, in this embodiment, an opening 21 is provided at the upper end of the tail material buffer device 20. The opening 21 is strip-shaped, and its width is exactly equal to the width of the track groove 31 on the fixed plate 30, ensuring that the opening 21 and the track groove 31 are matched in the lateral dimension without any width deviation. The strip-shaped opening 21 and the track groove 31 are on the same straight line, and the track groove 31 is located at the rear end of the opening 21. Taking the material conveying direction as a reference, after the material belt is output from the inside of the tail material buffer device 20, it first passes through the upper strip-shaped opening 21, and then enters the rear track groove 31 along the same straight line, forming a continuous conveying path of "the inside of the tail material buffer device 20 → the strip-shaped opening 21 → the track groove 31". The two are connected in the longitudinal direction (material belt conveying direction).

[0043] The equal width and straight line design of the opening 21 and the track groove 31 solves the path connection problem during the three-stage switching of "robotic arm traction → storage → output" in the operation process. Especially in the first stage when the material belt is pulled from the end away from the track groove 31 to the track groove 31, and in the second stage when the material belt is sent from the buffer device to the rear end, there is no jamming problem caused by width deviation or direction change.

[0044] Furthermore, the cover plate 40 extends from the end of the opening 21 to the end of the track groove 31.

[0045] Specifically, in this embodiment, the strip-shaped opening 21 at the upper end of the tail material buffer device 20 is aligned with the track trough 31 and located at the front end of the track trough 31. The cover plate 40 extends from the end of the opening 21 (i.e., the junction of the opening 21 and the track trough 31), receiving the conveying guidance of the material strip by the opening 21, forming a seamless transition of "opening 21 conveying → cover plate 40 covering track trough 31 conveying". The track trough 31 extends from the rear end of the opening 21 to the process of connecting new and old materials. The cover plate 40 covers the entire section of the track trough 31, neither exceeding the range of the track trough 31 and causing space waste, nor shortening the coverage length and causing the track trough 31 to be exposed, achieving equal-length coverage and precise alignment with the track trough 31.

[0046] Furthermore, the receiving module also includes a light-blocking box 60, which is mounted on the fixing plate 30 and located above the track groove 31.

[0047] Specifically, the light-blocking box 60 is a cavity structure that runs vertically through the interior. The side walls of the cavity are made of a material with light-shielding properties (such as matte black plastic, metal-coated sheet, etc.), which can effectively block external light from entering the cavity. The light-blocking box 60 is fixedly installed on the fixing plate 30, and the installation position corresponds to the preset detection position of the track groove 31—that is, directly above the material strip area that the tail material camera module 50 needs to capture and identify. The lower end of the cavity is precisely aligned vertically with the track groove 31 on the fixing plate 30. The material strip only passes through the track groove 31 covered by the cover plate 40 below the light-blocking box 60, achieving light-shielding coverage above the preset detection position of the track groove 31. This application uses the light-blocking box 60 to block external light from interfering with the preset detection position, preventing stray light from the external environment (such as workshop lighting, equipment indicator lights, etc.) from shining into the material strip detection area in the track groove 31, ensuring that the tail material camera module 50 obtains a clear image of the material strip.

[0048] Furthermore, the receiving module also includes a first light source and a second light source. The first light source is located below the track groove 31 and is positioned directly opposite the light-blocking box 60. The second light source is located on the inner wall of the light-blocking box 60 and is used to illuminate the area below the light-blocking box 60.

[0049] Specifically, both the first and second light sources are optical auxiliary components of the receiving module, serving the image acquisition of the tailing camera module 50. The first light source is fixedly installed below the track groove 31, with its installation position precisely corresponding to the light-blocking box 60—that is, its illumination direction is vertically upward, directly facing the preset detection position on the track groove 31 covered by the light-blocking box 60, ensuring that the light accurately acts on the material strip below that detection position. The second light source is installed on the inner wall of the light-blocking box 60, used to illuminate downwards from the light-blocking box 60. This solution, through the cooperation of the light-blocking box 60 and the two sets of illumination modules, enables the tailing camera module 50 to acquire accurate and clear images, improving the accuracy of recognition.

[0050] Furthermore, the receiving module also includes a bracket 70, which is mounted on the mounting base 10, and the tail material camera module 50 is connected to the bracket 70.

[0051] In this embodiment, the tail material camera module 50 is mounted on the bracket 70 via a displacement component. The displacement component can adopt a structure such as a linear guide rail, which supports adjustment in the horizontal and vertical directions, so that the camera lens can be accurately aligned with the preset detection position of the track groove 31 covered by the light-blocking box 60.

[0052] Furthermore, the receiving module also includes a tail material cutting component 80 installed on the mounting base 10. The tail material cutting component 80 is set corresponding to the track groove 31 and is movable up and down to cut the tail material on the track groove 31. The tail material cutting component is located at the rear end of the light-blocking box 60, and the cover plate 40 has a notch 42 at the position corresponding to the tail material cutting component.

[0053] Specifically, the tail material cutting component 80 is mounted on the mounting base 10 and is positioned corresponding to the track groove 31. The tail material cutting component 80 is located at the rear end of the light-blocking box 60, and the two are arranged in a "connected front and rear" layout along the conveying direction of the track groove 31, with the spacing adapted to the conveying speed of the material belt and the recognition response time. This layout ensures that after the material belt completes the blank area recognition below the light-blocking box 60, it can be conveyed to the cutting component at the rear end, avoiding asynchronous "recognition-cutting" caused by improper spacing (such as the material belt being conveyed too fast and missing the cutting position, or too slow and causing accumulation), forming a closed loop of "recognition positioning-precise cutting" process. The notch 42 of the cover plate 40 is a "avoidance structure" designed specifically for the tail material cutting assembly 80. Its position corresponds precisely to the cutting area of ​​the cutting assembly. When the cutting blade moves up and down, the blade can move completely within the range of the notch 42. It will not touch the edge of the cover plate 40 and cause damage, nor will the cutting action be affected by the cover plate 40. At the same time, the notch 42 is only opened at the corresponding position of the tail material cutting assembly. The rest of the cover plate 40 still covers the track groove 31, ensuring that the material strip is still constrained by the cover plate 40 during the conveying process (before reaching the cutting area) and avoids deviation.

[0054] It should be noted that in this embodiment, the receiving module further includes a head camera module 90, a head cutting component 91, and a film wrapping module 92. The head camera module 90 is used to identify the blank portion of the new material strip. The head cutting component is used to cut the blank portion of the new material strip. The film wrapping module 92 is located at the rear end of the tail material cutting component 80 and is used to connect the old and new material strips together. The new material tray is moved to the head cutting component 91 via a corresponding transfer device, and after the blank portion is cut, it is transported to the film wrapping module 92 to connect the old and new materials.
