Description

Technical Field

[0001] This utility model belongs to the field of mobile phone case manufacturing, and specifically relates to a mobile phone case manufacturing fixture and a quick adjustment structure. Background Technology

[0002] Mobile phone case production refers to the process of turning raw materials into accessories used to protect mobile phone casings through a series of processing techniques. Mobile phone case production typically includes design, mold making, injection molding or CNC machining, surface treatment (such as spraying, electroplating, UV coating), printing, and quality inspection. Common materials include plastics (such as PC, TPU), metals, glass, or composite materials. In the mobile phone case production process, traditional clamping devices mostly use mechanical clamping methods. This method has significant drawbacks in practical applications. First, mechanical clamping usually relies on rigid contact, with the clamp or pressure block directly contacting the surface of the mobile phone case. During clamping or movement, uneven pressure or friction can easily cause minor scratches, especially on high-gloss or mirror-finished cases, where even slight scratches can leave visible marks. Therefore, we aim to design a mobile phone case production clamp and a quick-adjustment structure to solve this problem. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a mobile phone case production fixture and quick adjustment structure to solve the problems mentioned in the background technology.

[0004] This utility model is achieved through the following technical solution: a mobile phone case production fixture and quick adjustment structure, including: a base, a clamping mechanism for adsorbing and clamping the mobile phone case is provided on the upper side of the base, and a dust collection mechanism for collecting processing dust is provided on the clamping mechanism.

[0005] The clamping mechanism includes a clamping suction cup, which has a hollow structure and several air inlets at the top. A vacuum valve for adjusting pressure is provided on the front side of the clamping suction cup. A support ring is fixedly connected inside the air inlets. A sealing block is elastically connected to the support ring by a spring. A sealing ring is also fixedly connected to the support ring. By using negative pressure to clamp the suction cup, the phone case is adsorbed by negative pressure, without the need for physical squeezing or clamping. This avoids scratches, indentations or deformations that may be caused by traditional clamps, and is especially suitable for high-gloss surfaces, coatings or brittle materials.

[0006] In a preferred embodiment, the upper surface of the clamping suction cup is provided with a rubber sealing gasket for protecting the surface of the phone case and improving the sealing between the surface of the phone case and the surface of the clamping suction cup.

[0007] In a preferred embodiment, a filter plate is slidably fitted inside the air inlet of the clamping suction cup to prevent debris from entering the inside of the clamping suction cup, and grooves for installation and limiting are provided on both sides of the filter plate.

[0008] In a preferred embodiment, a locking block is slidably sleeved inside the clamping suction cup, and a second spring is provided inside the clamping suction cup. The locking block cooperates with the groove of the filter plate for limiting and fixing. When disassembling the filter plate, the filter plate is pushed upward and the locking block is squeezed to compress and deform the second spring, thereby facilitating the disassembly and cleaning of the filter plate.

[0009] In a preferred embodiment, one end of the second spring is fixedly connected to the locking block, and the other end of the second spring is fixedly connected to the inside of the clamping suction cup. The elastic force of the second spring keeps the locking block inserted into the groove of the filter plate.

[0010] In a preferred embodiment, the dust collection mechanism includes a support frame, which is fixedly connected to the rear surface of the suction cup. A connecting block is hinged to the upper end of the support frame, and a dust collection hood is fixedly connected to the connecting block. By setting up the dust collection mechanism, debris during the production process is prevented from accumulating on the surface of the suction cup.

[0011] In a preferred embodiment, the dust collection mechanism further includes a cylinder, one end of which is hinged to the support frame, and the telescopic end of which is hinged to the connecting block. By setting up the cylinder, the angle of the dust collection hood can be adjusted by extending and retracting the telescopic end of the cylinder, thereby accurately capturing dust and improving dust collection efficiency.

[0012] In a preferred embodiment, a dust collection pipe is fixedly connected to the rear side of the dust collection hood and the dust collection pipe is connected to the interior of the dust collection hood. The middle section of the dust collection pipe is a telescopic structure that facilitates connection with external dust collection equipment.

[0013] After adopting the above technical solution, the beneficial effects of this utility model are:

[0014] 1. By using an external vacuum pump to create negative pressure in the internal cavity of the clamping suction cup, a sealed space is formed between the workpiece and the contact surface of the clamping cup. The pressure difference between atmospheric pressure and the vacuum chamber generates an adsorption force, thereby firmly fixing the phone case and avoiding scratches, indentations or deformations that may be caused by traditional clamps. It is especially suitable for high-gloss surfaces, coatings or brittle materials.

[0015] 2. By setting up a dust collection mechanism with an angle adjustment structure, the angle of the dust collection hood can be adjusted according to the processing position, thereby accurately capturing dust and improving dust collection efficiency. Attached Figure Description

[0024] 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.

[0025] Please see Figures 1 to 3 As the first embodiment of this utility model:

[0026] A mobile phone case production fixture and quick adjustment structure includes: a base 1, a clamping mechanism 2 for adsorbing and holding the mobile phone case on the upper side of the base 1, and a dust collection mechanism 3 for collecting processing dust on the clamping mechanism 2.

[0027] The clamping mechanism 2 includes a clamping suction cup 21, which has a hollow structure and several air inlets at the top. A vacuum valve for adjusting pressure is provided on the front side of the clamping suction cup 21. A support ring 22 is fixedly connected inside the air inlet. A sealing block 23 is elastically connected to the support ring 22 by a spring 24. A sealing ring 25 is also fixedly connected to the support ring 22. By using negative pressure to clamp the suction cup, the phone case is adsorbed by negative pressure without physical squeezing or clamping, avoiding scratches, indentations or deformations that may be caused by traditional clamps. It is especially suitable for high-gloss surfaces, coatings or brittle materials.

[0028] The upper surface of the clamping suction cup 21 is provided with a rubber sealing gasket 29 for protecting the surface of the phone case and improving the sealing between the surface of the phone case and the surface of the clamping suction cup 21.

[0029] The air inlet of the clamping suction cup 21 is fitted with a filter plate 26 to prevent debris from entering the interior of the clamping suction cup 21. Grooves for installation and positioning are provided on both sides of the filter plate 26.

[0030] The suction cup 21 is also fitted with a sliding block 27. The suction cup 21 is equipped with a second spring 28. The block 27 cooperates with the groove of the filter plate 26 for limiting and fixing. When disassembling the filter plate 26, the filter plate 26 is pushed upward and the block 27 is squeezed to compress and deform the second spring 28, thereby facilitating the disassembly and cleaning of the filter plate 26.

[0031] One end of the second spring 28 is fixedly connected to the locking block 27, and the other end of the second spring 28 is fixedly connected to the inside of the clamping suction cup 21. The elastic force of the second spring 28 keeps the locking block 27 inserted into the groove of the filter plate 26.

[0032] Specifically, firstly, an external vacuum pump is connected to the vacuum valve on the front side of the clamping suction cup 21 through a pipe. When clamping a mobile phone case, the mobile phone case is placed on the surface of the clamping suction cup 21 and the air inlet is covered. Then, the external vacuum pump is started to generate negative pressure in the internal cavity of the clamping suction cup 21, so that the contact surface between the workpiece and the clamping cup forms a sealed space. The pressure difference between atmospheric pressure and vacuum chamber generates adsorption force, thereby firmly fixing the mobile phone case and avoiding scratches, indentations or deformations that may be caused by traditional clamps. It is especially suitable for high-gloss surfaces, coatings or brittle materials. The uncovered air inlet drives the sealing block 23 to move downward during the high-speed air flow until the lower surface of the sealing block 23 contacts the sealing ring 25, thereby forming a sealed space and avoiding local air leakage that could lead to clamping failure.

[0033] Please see Figure 1 as well as Figure 4As a second embodiment of the present invention: based on the description in the above embodiments, the dust collection mechanism 3 further includes a support frame 31, which is fixedly connected to the rear surface of the clamping suction cup 21. A connecting block 32 is hinged to the upper end of the support frame 31, and a dust collection cover 33 is fixedly connected to the connecting block 32. By setting the dust collection mechanism 3, debris during the production process is prevented from accumulating on the surface of the clamping suction cup 21.

[0034] The dust collection mechanism 3 also includes a cylinder 34. One end of the cylinder 34 is hinged to the support frame 31, and the telescopic end of the cylinder 34 is hinged to the connecting block 32. By setting the cylinder 34, the angle of the dust collection hood 33 can be adjusted by extending and retracting the telescopic end of the cylinder 34, thereby accurately capturing dust and improving dust collection efficiency.

[0035] A dust collection pipe 35 is fixedly connected to the rear side of the dust collection hood 33 and the dust collection pipe 35 is connected to the interior of the dust collection hood 33. The middle section of the dust collection pipe 35 is a telescopic structure that facilitates connection with external dust collection equipment.

[0036] Specifically, during the polishing stage of mobile phone case production, high-speed friction causes fine particles to fall off the material surface, generating debris. Operators can connect an external negative pressure dust collection device to the dust collection pipe 35, and then collect the debris generated during the processing through the dust collection hood 33 to prevent it from accumulating on the surface of the clamping suction cup 21 and the sealing gasket 29. This prevents the debris from hindering the close contact between the suction cup and the workpiece surface, resulting in poor sealing, insufficient vacuum, and significantly weakened adsorption force.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
