Description

Technical Field

[0001] This invention relates to a silent cabin for assembly lines. Background Technology

[0002] A loudspeaker, also known as a horn in everyday life, is a basic electroacoustic conversion device that converts electrical energy into mechanical energy. A miniature loudspeaker, as the name suggests, is a scaled-down version of a traditional loudspeaker; in the electroacoustic industry, it typically refers to a loudspeaker with a diameter of less than 40 millimeters along its long axis. Miniature loudspeakers are ubiquitous in daily life, found in laptops, mobile phones, car audio systems, and televisions. They are also widely used in cinemas, stadiums, theaters, and children's toys. With the rapid development of science and technology, information technology, and digitalization, the market demand for consumer electronics products such as digital cameras, flat-screen TVs, and laptops has far exceeded that of traditional consumer products. These products require sound testing, making them the largest consumer goods category. This has led to significant development in sound testing, both in terms of quality and quantity.

[0003] The sound quality of electronic products cannot be directly measured indoors because the walls and surfaces of objects within the room reflect sound, and there is also various external environmental noise. The microphone receives not only the direct sound emitted by the speaker but also various reflected sounds and interference from environmental noise. Therefore, speaker testing needs to be conducted in an interference-free, ideal environment, i.e., a "free sound field." In this space, the medium through which sound waves propagate can spread uniformly and infinitely in all directions, without reflections from obstacles or interference from environmental noise. However, this free sound field only exists under ideal conditions. To ensure that speaker testing is free from any interference, an approximate free field space must be created.

[0004] For audio quality testing of laptops and mobile phones, or noise testing of motors or compressors on the production line, it is necessary to connect with the production line. Therefore, an automated soundproof chamber needs to be designed to connect with the production line. Summary of the Invention

[0005] The purpose of this invention is to provide a silent cabin for production lines, which solves the problem of how to adapt to production lines.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] This invention provides a silent assembly line cabin, comprising an outer casing and an inner casing disposed within the outer casing. The outer casing has external doors that can slide up and down on opposite sides, and the inner casing also has corresponding internal doors that can slide up and down. A soundproof space exists between the external doors and the corresponding internal doors. A transmission platform is disposed within the inner casing. The transmission platform includes a closed-loop belt, horizontal rollers supported at both ends of the belt, and lifting rollers that are raised and lowered between the horizontal rollers. The horizontal rollers are connected by elastic telescopic elements, the length of which is adjustable, allowing the belt to extend through the inner and outer doors to both sides via telescopic movement.

[0008] Preferably, the elastic telescopic element includes a telescopic sleeve and a sliding rod. The telescopic sleeve includes a base plate and a sleeve extending distally from the periphery of the base plate. The sliding rod is slidably disposed within the sleeve in the proximal direction. The distal end of the sleeve has an opening, and the sliding rod extends beyond the opening. A spring and a spring force adjustment mechanism are disposed within the sleeve in the space between the base plate and the inner end of the sliding rod. The spring force adjustment mechanism includes a slider with a receiving groove at one end and an adjustment block with at least a partial tip inserted into the receiving groove. The cross-sectional dimension of the adjustment block decreases in the direction of the slider to have the tip. The slider and the adjustment block are distributed in the proximal direction. Multiple sliders are disposed, and the inner diameters of the receiving grooves within the sliders are different to adjust the spatial length occupied by the sliders and the adjustment blocks.

[0009] Furthermore, a piston plate is provided at the inner end of the sliding rod, and the outer edge of the piston plate is in clearance fit with the inner wall of the sleeve.

[0010] Furthermore, a detachable retaining ring is provided at the opening of the sleeve, which blocks the movement path of the piston plate.

[0011] Furthermore, two telescopic sleeves are provided, with their openings facing each other, and both ends of the sliding rod extending into the two telescopic sleeves respectively.

[0012] Furthermore, both of the telescopic sleeves have connecting rods attached to their outer bottom plates for connection.

[0013] Furthermore, the sliding rod and the telescopic sleeve are rotatably configured.

[0014] Preferably, the outer door and the inner door are provided with sliding grooves on the corresponding box walls, and the outer door and the inner door are slidably disposed in the corresponding sliding grooves.

[0015] Preferably, cylinders are provided along the wall surface of the outer and inner casings, and the driving end of the cylinders is connected to the outer door or the inner door.

[0016] Furthermore, each of the outer and inner doors is driven by two parallel cylinders.

[0017] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art:

[0018] The silent production line chamber of this invention comprises an outer casing and an inner casing, with an outer door and an inner door on opposite sides of each casing. A conveyor platform within the inner casing utilizes elastic telescopic elements to allow a belt to pass through both the inner and outer doors and can be retracted into the inner casing for testing. This allows for material feeding from one side of the silent chamber and output from the other, facilitating integration with the production line. The integration with the production line during feeding or output is achieved through a retractable conveyor platform, whose belt extends or retracts into the silent chamber under the elastic telescopic effect of the elements. This facilitates the inspection of items such as laptops and mobile phones on the production line. Attached Figure Description

[0044] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0046] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0047] like Figure 1 and Figure 2 The illustrated silent chamber for the production line includes an outer casing 21, an inner casing 22, a transfer platform 10, and testing components not shown. Soundproofing panels installed on the walls of the outer casing 21 or inner casing 22 are not shown. The object to be tested (laptop, mobile phone, etc.) is placed on the transfer platform 10 for testing. The outer casing 21 and inner casing 22 provide a near-free-field space.

[0048] like Figure 2 and Figure 3 The inner housing 22 is housed within the outer housing 21. The inner housing 22 has inner doors 221 on opposite sides, and the outer housing 21 has outer doors 211 on opposite sides. The inner doors 221 and outer doors 211 are positioned correspondingly. A soundproof space 23 exists between the inner doors 221 and outer doors 211. The inner doors 221 and outer doors 211 are configured for material feeding from side B and material output from side C. The objects to be inspected (laptops, mobile phones, etc.) are fed from side B and output from side C. Sides B and C connect to the production line. The transfer platform 10 can extend and retract to both sides to connect to the production line.

[0049] Both the outer door 211 and the inner door 221 are designed to slide up and down, and are driven by cylinders 25 respectively. Figure 4 Each outer door 211 and inner door 221 is driven by two cylinders 25 to improve door stability. The cylinders 25 are connected to the inner walls of the outer housing 21 and inner housing 22, and are arranged along the wall surface. The drive end of the cylinder 25 is connected to either the outer door 211 or the inner door 221. Figure 2 and Figure 3 The outer door 211 and the inner door 221 are provided with sliding grooves 24 on the corresponding box walls, and the outer door 211 and the inner door 221 are slidably disposed in the corresponding sliding grooves 24.

[0050] like Figure 5 The transmission platform 10 shown has four rollers 7 wrapped around a belt 8 in a closed loop. Each roller 7 includes two horizontal rollers 71 and two lifting rollers 72, with the two lifting rollers 72 driven by a lifting rod 9. Two horizontal rollers 71, distributed at both ends horizontally, are connected to both ends of an elastic telescopic element 20, with each end of the horizontal roller 71 connected to the elastic telescopic element 20. The two lifting rollers 72 move up and down within the space between the two horizontal rollers 71. The elastic telescopic element 20 includes two telescopic sleeves 1 connected by a sliding rod 2, with a connecting rod 6 connected to the outer side of each telescopic sleeve 1. The connecting rod 6 is connected to the horizontal rollers 71. When the lifting rod 9 descends, the belt 8 flattens under the tension of the elastic telescopic element 20, causing the inner door 221 and outer door 211 to extend outwards from both sides of the belt 8 (see...). Figure 2 This allows it to connect with the production line. When the lifting rod 9 rises, the belt 8 narrows and enters the inner box 22.

[0051] like Figure 6 and Figure 7 The elastic telescopic element 20 includes a telescopic sleeve 1 and a sliding rod 2. The telescopic sleeve 1 includes a base plate 11 and a sleeve 12 extending distally from the periphery of the base plate 11 (towards the center point of the elastic telescopic element 20). An inner cavity is formed within the sleeve 12. The sliding rod 2 is slidably disposed within the sleeve 12. The distal end of the sleeve 12 has an opening 121. The sliding rod 2 extends out of the opening 121.

[0052] A piston plate 5 is provided at the inner end of the sliding rod 2, and the outer edge of the piston plate 5 is clearance-fitted with the inner wall of the sleeve 12. A detachable retaining ring 13 is provided at the opening 121 of the sleeve 12. The retaining ring 13 blocks the movement path of the piston plate 5 and prevents the piston plate 5 from dislodging. The components inside the sleeve 12 can be removed by removing the retaining ring 13. The sliding rod 2 and the telescopic sleeve 1 are rotatably configured, and the sliding rod 2 can rotate around the axis of the telescopic sleeve 1, so that the elastic telescopic element 20 can be twisted to better fit the horizontal roller 71.

[0053] The sleeve 12 is also equipped with a spring 3 and a spring force adjustment mechanism 4. The spring 3 and the spring force adjustment mechanism 4 are distributed in the space between the base plate 11 and the inner end of the sliding rod 2. The spring 3 is pre-tensioned, that is, it is arranged in a compressed state in the sleeve 12. The spring force adjustment mechanism 4 includes a slider 41 and an adjusting block 42. The slider 41 has a receiving groove 411. The adjusting block 42 has a tip 421. The cross-sectional dimension of the adjusting block 42 decreases in the direction of the slider 41, thus having a tip 421. The slider 41 and the adjusting block 42 are distributed in the length direction of the sleeve 12. Multiple sliders 41 are arranged in a selective manner in the sleeve 12, and the inner diameter of the receiving groove 411 in different sliders 41 is different. The receiving grooves 411 with different inner diameters can achieve different insertion depths of the tip 421 into the receiving groove 411, thereby adjusting the spatial length occupied by the sliders 41 and the adjusting blocks 42, and thus adjusting the preload of the spring 3. A connecting rod 6 is also provided on the outer side of the base plate 11. The connecting rod 6 is used for external connection. A connecting hole 61 is provided at the outer end of the connecting rod 6 (see...). Figure 6 ), connecting hole 61 is used to connect with Figure 5 The horizontal rollers 71 are connected. At least one of the horizontal rollers 71 is a drive roller for driving the belt 8 to rotate in order to transport the object to be inspected (laptop, mobile phone, etc.).

[0054] In this example, see Figure 6 There are two telescopic sleeves 1, with the openings 121 of the two telescopic sleeves 1 facing each other, and the two ends of the sliding rod 2 extending into the two telescopic sleeves 1 respectively.

[0055] In this example, the elastic telescopic element 20 adjusts the depth of the tip 421 of the adjusting block 42 inserted into the slider 41 by replacing the slider 41, thereby adjusting the spatial length occupied by the adjusting block 42 and the slider 41, and thus adjusting the preload of the spring 3.

[0056] In summary, the silent assembly line cabin in this example is equipped with an outer door 211 and an inner door 221 on both sides of the outer casing 21 and the inner casing 22, respectively, and the internal transmission platform 10 has a telescopic function, thus enabling it to connect with the production line.

[0057] It has the following advantages:

[0058] (1) To enable the sound emitted by electronic products to be clearly collected without being affected by external interference.

[0059] (2) Good automation effect, which can be easily connected with automated production lines.

[0060] (3) Pure tone - not affected by external sounds.

[0061] The above embodiments are only for illustrating the technical concept and features of the present invention. Their purpose is to enable those skilled in the art to understand the content of the present invention and implement it accordingly. They should not be used to limit the scope of protection of the present invention. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
