Description

Technical Field

[0001] This utility model belongs to the field of barcode reader technology, specifically relating to a barcode reader structure with adjustable light source angle. Background Technology

[0002] A barcode reader is an industrial device used to automatically identify data from carriers such as 1D / 2D barcodes and RFID tags. Its core functions include product tracking and tracing, production control, and data acquisition. It is widely used in industries such as automobile manufacturing, logistics warehousing, and pharmaceuticals.

[0003] Barcode readers are equipped with light sources for supplementary lighting. The presence of these light sources provides a brightness environment to ensure that the barcode reading module can read barcodes normally. However, in existing barcode readers, the light sources are all built-in and fixed inside the reader. Therefore, when scanning barcodes at different locations on the object, the angle and position of the light source cannot be adaptively adjusted according to the actual situation, which has certain limitations in use. To address this, we propose a barcode reader structure with adjustable light source angle. Utility Model Content

[0004] The purpose of this invention is to provide a barcode reader structure with an adjustable light source angle, in order to solve the problem mentioned in the background art that the light source lamps of existing barcode readers are all built-in and fixedly installed inside the barcode reader. Therefore, when scanning barcodes at different positions on the object to be scanned, the angle and position of the light source lamp cannot be adaptively adjusted according to the actual situation, which has certain limitations in use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a barcode reader structure with adjustable light source angle, comprising a barcode reader body, a mounting shell provided on the surface of the barcode reader body, and mounting plates fixedly mounted on both the left and right ends of the mounting shell. The mounting plates are fitted to the sides of the barcode reader body and are movably connected to the barcode reader body. Two rotating shafts are rotatably mounted inside the mounting shell, and a threaded rod is fixedly mounted between the two rotating shafts. One of the rotating shafts extends out of the mounting shell and is fixedly mounted with a knob. A threaded plate is threadedly mounted on the outer surface of the threaded rod, and a connecting plate is fixedly mounted on the side of the threaded plate. The connecting plate extends out of the mounting shell through a channel opened on the side of the mounting shell. A mounting base is fixedly installed, on which a second rotating shaft is rotatably mounted. A rotating seat is fixedly mounted on the outer surface of the second rotating shaft. A light source is provided on the side of the rotating seat. Two locking plates are provided on the side of the rotating seat, respectively attached to the upper and lower sides of the light source. Locking blocks are fixedly installed on the opposite sides of the two locking plates. Locking slots for the locking blocks to be locked into are provided on the upper and lower sides of the light source. The locking plate at the lower position is fixedly installed on the side of the rotating seat, and the locking plate at the upper position is movably disposed on the side of the rotating seat. A power-on connector is provided on the side of the reader body, which is used to connect to an external cable to achieve data communication.

[0006] The above solution utilizes a mounting shell in conjunction with a mounting plate. The mounting shell is detachably mounted on the barcode reader body via the mounting plate. The rotation of the threaded rod inside the mounting shell drives the threaded plate to move horizontally, thereby adjusting the horizontal position of the light source via the connecting plate, mounting base, and rotating base. Simultaneously, the tilt angle of the light source is adjusted using the second rotating shaft. This allows for adaptive adjustment of the light source's angle position based on the location of the barcode on the object to be scanned. The external mounting of the light source facilitates operation and adjustment. The use of a locking plate and a locking block, with one locking plate fixed and the other movable, along with the locking block, secures the light source, facilitating its disassembly and use.

[0007] In a preferred embodiment, several locking balls are fixedly installed on both the left and right sides of the barcode reader body, and a spherical groove is opened on the side of the mounting plate facing the barcode reader body, and the locking balls are used in conjunction with the spherical groove.

[0008] By using the above solution, the locking ball and spherical groove can be used together to complete the convenient locking of the mounting plate. The locking structure is simple and the disassembly and assembly of the mounting shell is convenient.

[0009] In a preferred embodiment, an alignment plate is fixedly installed on one side of the card plate facing the main body of the barcode reader. Alignment slots are provided on both the left and right sides of the main body of the barcode reader, and the alignment plate is inserted into the inner wall of the alignment slot at the same side position.

[0010] By using the above scheme, the alignment plate and alignment groove are used together to ensure that the positioning ball and the spherical groove can be smoothly engaged when the mounting plate is inserted from top to bottom, which improves the convenience of the mounting operation and achieves a good alignment and guidance effect.

[0011] In a preferred embodiment, a guide rail is fixedly installed on the inner wall of the mounting shell, and a guide rail groove is provided on the side of the threaded plate, with the guide rail slidably installed on the inner wall of the guide rail groove.

[0012] With the above scheme, when the threaded rod rotates and drives the threaded plate to move, the threaded plate will slide stably on the surface of the guide rail through the guide rail groove. Therefore, the use of the guide rail can ensure that the horizontal movement of the threaded plate is stable and that it is not easy to tilt or wobble.

[0013] In a preferred embodiment, a fixing rod is fixedly installed on the side of the rotating seat. The surface of the fixing rod is threaded. An arc-shaped slide is provided on the mounting seat, which is coaxial with the rotating shaft. The fixing rod passes through the arc-shaped slide and is threadedly fitted with a fixing nut. The fixing nut is fitted and arranged on the side of the mounting seat.

[0014] Using the above solution, a fixed rod passes through the arc-shaped slide and is used in conjunction with a fixed nut. When the fixed nut is unscrewed, the rotating seat is unlocked. At this time, the rotating seat can rotate through the second rotating shaft to adjust the pitch angle of the light source. After adjustment, the fixed nut is screwed on to lock the position. The threaded connection has good stability and is not easy to loosen.

[0015] In one preferred embodiment, a number of sliders are fixedly installed on the side of the movable mounting plate, and a number of grooves are opened on the side of the rotating seat, with the sliders slidably installed on the inner wall of the grooves at corresponding positions.

[0016] By using the above scheme, the sliding block can be moved up and down stably by sliding within the groove.

[0017] In a preferred embodiment, a spring is fixedly mounted on the surface of the slider, the spring is located inside the slide groove, and the end of the spring away from the slider is fixedly mounted on the inner wall of the slide groove.

[0018] Using the above solution, the spring deforms when the locking plate slides upward, so the spring force can be used to drive the locking plate to move downward quickly, improving the convenience of locking operation.

[0019] In a preferred embodiment, the interface shape of both the slider and the groove is trapezoidal.

[0020] By adopting the above scheme, a trapezoidal slider is used in conjunction with a trapezoidal groove, which can prevent the locking plate from detaching from the rotating seat when sliding, thus achieving a limiting effect.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] This adjustable light source barcode reader structure uses a mounting shell in conjunction with a mounting plate. The mounting shell is detachably mounted on the barcode reader body via the mounting plate. The rotation of the threaded rod inside the mounting shell drives the threaded plate to move horizontally, thereby adjusting the horizontal position of the light source lamp through the connecting plate, mounting base, and rotating base. At the same time, the pitch angle of the light source lamp can be adjusted by the setting of the second rotating shaft. Thus, the angle position of the light source lamp can be adaptively adjusted according to the position of the barcode on the object to be scanned. Moreover, the light source lamp is externally mounted, which is convenient for operation and adjustment.

[0023] The adjustable light source reader structure uses a combination of a locking plate and a locking block. One locking plate is fixed and the other is movable. Together with the locking block, they lock into the locking slot, enabling convenient locking of the light source and facilitating disassembly and use of the light source.

[0032] Please see Figure 1-7 This utility model provides a reader structure with an adjustable light source angle, including a reader body 1. A mounting shell 2 is provided on the surface of the reader body 1. Mounting plates 3 are fixedly mounted on both ends of the mounting shell 2. The mounting plates 3 are fitted against the sides of the reader body 1 and are movably connected to it. Two rotating shafts 4 are rotatably mounted inside the mounting shell 2. A threaded rod 5 is fixedly mounted between the two rotating shafts 4. One of the rotating shafts 4 extends out of the mounting shell 2 and is fixedly mounted with a knob. A threaded plate 6 is threaded onto the outer surface of the threaded rod 5. A connecting plate 7 is fixedly mounted on the side of the threaded plate 6. The connecting plate 7 extends out of the mounting shell 2 through a channel opened on the side of the mounting shell 2 and is fixedly mounted with a mounting base 8. A rotating shaft 9 is rotatably mounted on the 8th inch. A rotating seat 10 is fixedly mounted on the outer surface of the rotating shaft 9. A light source 11 is provided on the side of the rotating seat 10. Two locking plates 12 are provided on the side of the rotating seat 10. The two locking plates 12 are respectively attached to the upper and lower sides of the light source 11. Locking blocks 13 are fixedly mounted on the opposite sides of the two locking plates 12. Locking slots for locking blocks 13 to be locked into are opened on the upper and lower sides of the light source 11. The locking plate 12 at the lower position is fixedly mounted on the side of the rotating seat 10, and the locking plate 12 at the upper position is movably mounted on the side of the rotating seat 10. A power-on connector 21 is provided on the side of the reader body 1. The power-on connector 21 is used to connect with external cables to achieve data communication.

[0033] The mounting shell 2 is used in conjunction with the mounting plate 3. The mounting shell 2 is detachably mounted on the barcode reader body 1 via the mounting plate 3. The rotation of the threaded rod 5 inside the mounting shell 2 drives the threaded plate 6 to move horizontally. This, in turn, adjusts the horizontal position of the light source 11 through the connecting plate 7, the mounting base 8, and the rotating base 10. At the same time, the tilt angle of the light source 11 is adjusted by the setting of the rotating shaft 9. Thus, the angle position of the light source can be adaptively adjusted according to the position of the barcode on the object to be scanned. The light source 11 is externally mounted for easy operation and adjustment. The two mounting plates 12 and 13 are used in conjunction, with one fixed and the other movable. The mounting plates 12 and 13 are engaged in the mounting slot to lock the light source 11, which facilitates the disassembly and use of the light source 11.

[0034] Several locking balls 14 are fixedly installed on both the left and right sides of the reader body 1. A spherical groove is opened on the side of the mounting plate 3 facing the reader body 1. The locking balls 14 and the spherical groove are used together. By using the locking balls 14 and the spherical groove together, the mounting plate 3 can be easily locked. The locking structure is simple and the disassembly and assembly of the mounting shell 2 are convenient.

[0035] A positioning plate 15 is fixedly installed on the side of the mounting plate 3 facing the main body 1 of the barcode reader. Positioning slots are provided on both the left and right sides of the main body 1 of the barcode reader. The positioning plate 15 is inserted into the inner wall of the positioning slot on the same side. By using the positioning plate 15 and the positioning slot together, the positioning ball 14 can be smoothly engaged with the spherical groove when the mounting plate 3 is inserted from top to bottom, which improves the convenience of the mounting operation and achieves a good positioning and guiding effect.

[0036] The inner wall of the mounting shell 2 is fixedly installed with a guide rail 16. The side of the threaded plate 6 is provided with a guide rail groove. The guide rail 16 is slidably installed on the inner wall of the guide rail groove. When the threaded rod 5 rotates and drives the threaded plate 6 to move, the threaded plate 6 will slide stably on the surface of the guide rail 16 through the guide rail groove. Therefore, the use of the guide rail 16 can ensure that the horizontal movement of the threaded plate 6 is stable and not prone to tilting or shaking.

[0037] A fixing rod 17 is fixedly installed on the side of the rotating seat 10. The surface of the fixing rod 17 is threaded. The mounting seat 8 has an arc-shaped slide rail that is coaxial with the second rotating shaft 9. The fixing rod 17 passes through the arc-shaped slide rail and is threaded with a fixing nut 18. The fixing nut 18 is fitted and arranged on the side of the mounting seat 8. The fixing rod 17 passes through the arc-shaped slide rail and works in conjunction with the fixing nut 18. When the fixing nut 18 is unscrewed, the rotating seat 10 is unlocked. At this time, the rotating seat 10 can rotate through the second rotating shaft 9 to realize the tilt angle adjustment of the light source 11. After the adjustment is completed, the fixing nut 18 is screwed on to lock the position. The threaded connection has good stability and is not easy to loosen.

[0038] The movable positioning plate 12 has several sliders 19 fixedly installed on its side, and the rotating seat 10 has several grooves on its side. The sliders 19 are slidably installed on the inner wall of the groove at the corresponding position. By sliding the sliders 19 in the groove, the movable positioning plate 12 can move up and down stably.

[0039] A spring 20 is fixedly installed on the surface of the slider 19. The spring 20 is located inside the slide groove. The end of the spring 20 away from the slider 19 is fixedly installed on the inner wall of the slide groove. When the locking plate 12 slides upward, the spring 20 deforms. Therefore, the elastic force of the spring 20 can drive the locking plate 12 to move downward quickly, improving the convenience of locking operation.

[0040] The interface shape of both the slider 19 and the slide groove is trapezoidal. The trapezoidal slider 19 is used in conjunction with the trapezoidal slide groove to prevent the locking plate 12 from detaching from the rotating seat 10 when it slides, thus achieving a limiting effect.

[0041] In use, the horizontal position and pitch angle of the light source 11 are adjusted according to the position of the barcode on the object to be scanned. For horizontal position adjustment, turning the knob drives the threaded rod 5 to rotate, which in turn drives the threaded plate 6 to move the connecting plate 7 horizontally. This, in turn, drives the mounting base 8 and the rotating base 10 to move the light source 11 horizontally. Once the desired position is reached, stop turning the knob. For pitch angle adjustment, unscrew the fixing nut 18. At this point, the rotating base 10 is unlocked and can rotate the light source 11 through the rotating shaft 9. After turning to the appropriate angle, tighten the fixing nut 18 to lock the position. Then, start the code reader body 1 and the light source 11 to read codes. When it is necessary to remove the mounting shell 2, pull the mounting shell 2 upward so that the locking ball 14 disengages from the spherical groove and the mounting shell 2 can be removed. When it is necessary to remove the light source 11, pull the upper locking plate 12 upward. The movement of the upper locking plate 12 drives the upper locking block 13 to disengage from the upper locking groove. At this time, slide the light source 11 upward so that the lower locking block 13 disengages from the lower locking groove, and then remove the light source 11 to complete the disassembly.
