Description

Technical Field

[0001] This utility model relates to the field of barcode reader heat dissipation technology, specifically an industrial fixed barcode reader. Background Technology

[0002] Industrial stationary barcode readers are highly automated barcode / QR code recognition devices designed specifically for harsh industrial environments. They are typically fixed to production lines, conveyor belts, or warehouse entrances, and automatically scan and recognize barcodes (such as 1D, 2D, and DPM codes) on the surfaces of moving or stationary objects using high-speed image acquisition and intelligent decoding algorithms, achieving real-time data collection with zero human intervention.

[0003] Most existing traditional barcode readers use an integrated housing design, with heat dissipation relying solely on fixed heat sinks on the housing surface or a single built-in fan for passive ventilation. When the barcode reader operates under high load for extended periods, internal heat buildup leads to overheating of the chip, easily causing decoding delays, data loss, and other malfunctions, severely impacting production continuity. Therefore, we propose an industrial fixed barcode reader. Utility Model Content

[0004] The purpose of this invention is to provide an industrial fixed barcode reader to solve the problem mentioned in the background art. Most existing traditional barcode readers adopt an integrated shell design, and heat dissipation relies solely on fixed heat dissipation fins on the surface of the shell or a single built-in fan for passive ventilation. When the barcode reader operates under high load for a long time, internal heat accumulates, causing the chip temperature to become too high, which can easily lead to decoding delays, data loss and other faults, seriously affecting the continuity of production.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an industrial fixed barcode reader, comprising: a barcode reader body, wherein a heat dissipation component is movably connected to the outer surface of the barcode reader body; The heat dissipation assembly includes a pull frame, a heat sink fixedly connected to the side surface of the pull frame, a fan assembly inside the heat sink, a sliding groove on the upper surface of the pull frame, a sliding block movably connected to the inner surface of the sliding groove, a spring post fixedly connected to the side surface of the sliding block, a connecting seat fixedly connected to the outer surface of the sliding block, a connecting shaft fixedly connected to the end of the connecting seat away from the sliding block, push-pull rods sleeved at the upper and lower ends of the connecting shaft, and a central shaft movably connected to the end of the push-pull rod away from the connecting shaft.

[0006] The sliding blocks are fixedly connected to both ends of the spring column in two groups, and the spring column is movably connected inside the pull frame.

[0007] The push-pull rod, connecting shaft, and connecting seat are connected in four sets of cross-shaped movable connections inside the central shaft.

[0008] The pull frame is arranged in two sets on both sides of the central axis. The pull frame is fixedly connected to the upper and lower ends of the heat sink in two sets. The pull frame and the heat sink are symmetrically clamped on both sides of the barcode reader body.

[0009] An adjustment assembly is fixedly connected to the center of the outer surface of the heat sink. The adjustment assembly includes a fixing ring. The fixing rings are fixedly connected in two sets at the center of the outer and inner surfaces of the heat sink. A guide post is fixedly connected to the side of the fixing ring away from the heat sink. A screw is connected through the inside of the guide post. A rotating handle is fixedly connected to one end of the screw. A soft rubber pad is fixedly connected to the other end of the screw. The soft rubber pad rests against the two sides of the barcode reader body.

[0010] The screw runs through the inner and outer sides of the heat sink.

[0011] This utility model has at least the following beneficial effects: 1. In use, this utility model combines a pull frame with a heat sink, utilizing a sliding block connected by a spring post within a sliding groove, along with a cross-linked structure of a connecting seat, connecting shaft, and push-pull rod, to achieve symmetrical elastic clamping of the heat sink onto the reader body. The buffering characteristics of the spring post ensure a tight fit of the heat sink while preventing rigid damage. The internal fan assembly can directly and efficiently dissipate heat from the reader surface, effectively improving the problems of poor contact or equipment damage caused by traditional heat dissipation devices.

[0012] 2. In use, this utility model utilizes a support structure formed by a fixing ring and guide post on the outer surface of the heat sink, with a screw passing through it and connecting a rotating handle and a soft rubber pad. Rotating the handle drives the screw to move axially, causing the soft rubber pad to press against the reader body. Combined with the elastic return of the spring post, this allows for stepless adjustment of the gap between the heat sink and the reader surface. This structure can flexibly switch between two modes: "close contact for efficient heat dissipation" and "increased gap for enhanced convection," adapting to the heat dissipation needs under different operating conditions and effectively improving the limitations of traditional heat dissipation devices, such as inconvenient adjustment and limited functionality.

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-4 This utility model provides a technical solution: an industrial fixed barcode reader, including: a barcode reader body 1, and a heat dissipation component 2 movably connected to the outer surface of the barcode reader body 1.

[0017] In use, by combining the pull frame 21 with the heat sink 22, and utilizing the sliding block 25 connected by the spring column 26 in the sliding groove 24, along with the cross-linking structure of the connecting seat 27, connecting shaft 28, and push-pull rod 29, the heat sink 22 achieves symmetrical elastic clamping of the barcode reader body 1. The buffering characteristics of the spring column 26 ensure that the heat sink 22 fits tightly while avoiding rigid damage. The internal fan assembly 23 can directly and efficiently dissipate heat from the barcode reader surface, effectively improving the problems of poor contact or equipment damage caused by traditional heat dissipation devices.

[0018] The heat dissipation assembly 2 includes a pull frame 21, a heat sink 22 is fixedly connected to the side surface of the pull frame 21, a fan assembly 23 is arranged inside the heat sink 22, a sliding groove 24 is opened on the upper surface of the pull frame 21, a sliding block 25 is movably connected to the inner surface of the sliding groove 24, a spring post 26 is fixedly connected to the side surface of the sliding block 25, a connecting seat 27 is fixedly connected to the outer surface of the sliding block 25, a connecting shaft 28 is fixedly connected to the end of the connecting seat 27 away from the sliding block 25, a push-pull rod 29 is sleeved at the upper and lower ends of the connecting shaft 28, and a central shaft 210 is movably connected to the end of the push-pull rod 29 away from the connecting shaft 28.

[0019] During the heat dissipation clamping process, two sets of pull brackets 21 are fixed to the upper and lower ends of the heat dissipation plate 22, respectively, and symmetrically clamped on both sides of the barcode reader body 1. Two sets of sliding blocks 25 are connected by spring columns 26 within the sliding grooves 24 on the upper surface of the pull brackets 21, allowing them to slide flexibly within the grooves. When the pull brackets 21 are pushed closer to the barcode reader body 1, the sliding blocks 25 move within the sliding grooves 24 under pressure, compressing the spring columns 26. The connecting seat 27 drives the connecting shaft 28 and the push-pull rod 29 to perform a cross-linking action around the central axis 210, causing the two sets of pull brackets 21 to move synchronously towards the center, thus attaching the heat dissipation plate 22 to the outer surface of the barcode reader body 1. After the fan assembly 23 inside the heat dissipation plate 22 is activated, it can directly blow air to dissipate heat from the surface of the barcode reader body 1. The elastic clamping force of the spring columns 26 ensures that the heat dissipation plate 22 is tightly attached while preventing damage to the barcode reader due to excessive clamping.

[0020] An adjustment assembly 3 is fixedly connected to the center of the outer surface of the heat sink 22. The adjustment assembly 3 includes a fixing ring 31. The fixing ring 31 is fixedly connected in two sets at the center of the outer surface and the inner surface of the heat sink 22. A guide post 32 is fixedly connected to the side of the fixing ring 31 away from the heat sink 22. A screw 33 is connected through the inside of the guide post 32. A rotating handle 34 is fixedly connected to one end of the screw 33. A soft rubber pad 35 is fixedly connected to the other end of the screw 33. The soft rubber pad 35 abuts against the two sides of the barcode reader body 1.

[0021] When the heat dissipation gap needs to be adjusted, it can be achieved through the adjustment component 3. The fixing ring 31 at the center of the outer surface of the heat dissipation plate 22 is connected to the guide post 32. The screw 33 passes through the guide post 32 and the heat dissipation plate 22, with one end connected to the rotating handle 34 and the other end provided with a soft rubber pad 35. When the rotating handle 34 is rotated, the screw 33 moves axially within the guide post 32, driving the soft rubber pad 35 to adjust the fitting gap between the heat dissipation plate 22 and the barcode reader body 1. When it is necessary to increase the heat dissipation gap to improve airflow, rotate the handle 34 in the reverse direction to lengthen the distance between the soft rubber pad 35 and the heat sink 22 and the reader body 1, thereby widening the gap between the heat sink 22 and the reader body 1 and promoting air convection. The heat sink 22 rebounds slightly under the elastic action of the spring column 26, so that the soft rubber pad 35 remains in contact with the side surface of the reader body 1. If it is necessary to reduce the gap and enhance heat dissipation contact, rotate the handle 34 in the forward direction to shorten the distance between the soft rubber pad 35 and the heat sink 22 and the reader body 1, thereby bringing the fan assembly 23 closer to the reader body 1 and enhancing the heat dissipation effect of the fan assembly 23 on the reader body 1, thus meeting the heat dissipation requirements under different operating conditions.
