Abstract
Description
Technical Field
[0001] This utility model relates to the field of antenna processing equipment technology, and in particular to an antenna spraying fixture. Background Technology
[0002] As a key component in wireless communication systems, antennas require surface coating to meet protection or aesthetic requirements. During the coating process, the antenna must be stably clamped and the non-coated areas must be precisely shielded.
[0003] In existing operating methods, antennas are fixed using general-purpose clamps or simple brackets. This method cannot guarantee that the antenna will be placed in the exact same position each time during repeated clamping, resulting in deviations in product positioning accuracy. Positioning deviations directly cause misalignment of the sprayed area, affecting the consistency of the product's appearance. At the same time, the protection of non-sprayed areas is mostly done by manually applying tape or using separate masking covers. This is not only cumbersome, but the masking edge contours are not clear enough, which can cause paint leakage and reduce the product yield. In addition, the locking and releasing structure of these clamps is mostly bolt fastening. Operators need to repeatedly tighten or loosen the bolts when picking up and placing products. The entire loading and unloading process is time-consuming and cannot meet the fast-paced requirements of mass production, which seriously restricts the overall production efficiency.
[0004] Therefore, this utility model proposes an antenna spraying fixture to overcome the shortcomings of the prior art. Utility Model Content
[0005] In view of the problems of insufficient product positioning, cumbersome masking operation, and low product loading and unloading efficiency in the existing antenna spraying fixture, this utility model aims to provide an antenna spraying fixture with an improved structure that can effectively solve the above problems.
[0006] This utility model provides an antenna spraying fixture, including a lower mold, an upper mold, and a positioning mechanism and a quick-release mechanism disposed between the lower mold and the upper mold.
[0007] The positioning mechanism includes a limiting block fixedly connected to the top of the lower mold and a positioning post fixedly connected to the bottom of the upper mold. The limiting block is slidably connected to the limiting groove on the product, and the positioning post is slidably connected to the positioning hole on the product.
[0008] The quick-release mechanism includes a fixed block fixedly connected to the outer wall of the lower mold, a rotating shaft rotatably connected to the upper mold, a locking block fixedly connected to the middle of the rotating shaft, and torsion springs fixedly connected at both ends to the inner wall of the upper mold and the rotating shaft, respectively. The locking block can engage or disengage from the fixed block under the action of the torsion spring.
[0009] Preferably, a shielding frame is also fixedly connected to the top of the upper mold, and the shielding frame and the body of the upper mold together form a shielding surface for shielding the non-painted areas of the product.
[0010] Preferably, the bottom of the lower mold is also fixedly connected to a connecting column for mounting the antenna spraying fixture onto an external device.
[0011] Preferably, a rubber pad is also fixedly connected to the lower outer wall of the card block, and the rubber pad is used to provide cushioning when the card block is engaged with the fixing block.
[0012] Preferably, a protective shell is fixedly connected to the outer wall of the upper mold. The protective shell is hollow and covers the outside of the rotating shaft, the locking block and the torsion spring to protect the internal structure.
[0013] Preferably, the torsion spring is in a pre-tightened contraction state, and the applied torsional force drives the locking block to remain locked in the position of engaging with the fixing block.
[0014] Preferably, the cooperation between the limiting block and the limiting groove is used to initially limit the product, and the cooperation between the positioning post and the positioning hole is used to precisely position the product.
[0015] Preferably, the positioning hole of the product is provided with a limiting groove on both the left and right sides to cooperate with the limiting block, so as to enhance the stability of positioning.
[0016] This utility model has the following beneficial effects:
[0017] 1. This utility model solves the problem of inaccurate positioning and easy displacement of antenna products in the prior art by setting a limiting block on the lower mold and a positioning post on the upper mold, which are respectively precisely matched with the limiting groove and positioning hole on the product. It achieves the effect of dual positioning, stable clamping and high spraying accuracy of the product.
[0018] 2. This utility model, by setting a quick-release mechanism with a locking block driven by a torsion spring, enables the upper and lower molds to be quickly locked and released by rotating the locking block. This solves the problem of cumbersome and time-consuming operation of clamp loading and unloading products in the prior art, and achieves the effect of simplifying operation steps, shortening the single-piece operation time, and significantly improving overall production efficiency.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.
[0028] Example:
[0029] Please refer to Figures 1 to 6 This utility model provides an antenna spraying fixture, which aims to solve the problems of low positioning accuracy, cumbersome shielding operation and low product loading and unloading efficiency of the existing antenna spraying fixture.
[0030] Please refer to Figure 1 and Figure 2 As shown, an antenna coating fixture includes a lower mold 204 and an upper mold 207 disposed above the lower mold 204. The lower mold 204 serves as the mounting base for the entire fixture and is used to support the product 1. The upper mold 207 cooperates with the lower mold 204 to position, clamp, and shield the product 1.
[0031] Please refer to Figures 2 to 5The positioning mechanism 2 includes a limiting block 203 fixedly connected to the top of the lower mold 204 and a positioning post 206 fixedly connected to the bottom of the upper mold 207. The product 1 has a positioning hole 201 that cooperates with the positioning post 206 and a limiting groove 202 that cooperates with the limiting block 203. During assembly, the limiting block 203 is slidably connected to the limiting groove 202 of the product 1, and the positioning post 206 is slidably connected to the positioning hole 201 of the product 1. The cooperation between the limiting block 203 and the limiting groove 202 is used to initially limit the product 1, and the cooperation between the positioning post 206 and the positioning hole 201 is used to accurately position the product 1.
[0032] Please refer to Figure 1 and Figure 6 The quick-release mechanism 3 is used to lock and release the upper mold 207 and the lower mold 204. The quick-release mechanism 3 includes a fixing block 306 fixedly connected to the outer wall of the lower mold 204, a rotating shaft 302 rotatably connected to the inner wall of the upper mold 207, a locking block 303 fixedly connected to the middle of the rotating shaft 302, and a torsion spring 301 fixedly connected to the inner wall of the upper mold 207 and the rotating shaft 302 at both ends respectively. The locking block 303 can engage or disengage from the fixing block 306 under the action of the torsion spring 301. This locking structure driven by the spring lock block 303 ensures that the upper mold 207 and the lower mold 204 can be quickly assembled and disassembled, improving the operating efficiency.
[0033] As a preferred embodiment, to enhance the masking effect on the non-coated areas of product 1, please refer to... Figure 5 The top of the upper mold 207 is also fixedly connected to a shielding frame 208. The shielding frame 208 and the body of the upper mold 207 together form a shielding surface for shielding the non-sprayed area of the product 1.
[0034] As a preferred embodiment, to facilitate the stable mounting of the entire antenna coating fixture on an external workbench or production line, please refer to... Figure 4 The bottom of the lower mold 204 is also fixedly connected to a connecting column 205.
[0035] As a preferred embodiment, in order to reduce the impact and wear when the locking block 303 and the fixing block 306 are engaged, and to extend the service life, please refer to... Figure 6 A rubber pad 304 is also fixedly connected to the lower outer wall of the card block 303.
[0036] As a preferred embodiment, in order to provide effective protection for the internal components of the quick-release mechanism 3 and prevent external debris from affecting normal operation, please refer to... Figure 1 The outer wall of the upper mold 207 is also fixedly connected with a protective shell 305. The protective shell 305 is hollow and covers the outside of the rotating shaft 302, the locking block 303 and the torsion spring 301.
[0037] As a preferred embodiment, in order to ensure that the quick-release mechanism 3 can maintain a reliable locking state when no one is operating it, the torsion spring 301 is in a pre-tightened contraction state, and the continuous torsional force generated can drive the locking block 303 to be constantly pressed against the fixing block 306.
[0038] As a preferred implementation method, to further improve the stability and reliability of positioning, please refer to... Figure 3 The positioning hole 201 of product 1 is provided with limiting grooves 202 on both the left and right sides to cooperate with the limiting block 203.
[0039] Working principle: When product 1 needs to be painted, product 1 is first placed on the lower mold 204, so that the limiting groove 202 on product 1 is aligned with the limiting block 203 on the lower mold 204 and slides in to achieve initial limiting and fixing. Then, the upper mold 207 is placed on product 1, and the positioning pin 206 at the bottom of the upper mold 207 will be precisely inserted into the positioning hole 201 of product 1 to complete the final precise positioning. At this time, the upper mold 207 and the top shield 208 completely cover the parts of product 1 that do not need to be painted. Then, the operator rotates the locking block 303 so that the locking block 303 passes over and locks onto the fixing block 306 on the side of the lower mold 204.
[0040] After release, the torsion spring 301, which is in a pre-tightened state, releases its torsional force, driving the locking block 303 to remain locked to the fixing block 306, thereby firmly locking the upper mold 207 and the lower mold 204 together and completing the clamping of product 1. When product 1 needs to be quickly disassembled, simply rotate the locking block 303 outward to disengage it from the fixing block 306, and the upper mold 207 can be directly removed. Through the coordinated action of the positioning mechanism 2 and the quick-release mechanism 3, this utility model solves the problems of inaccurate positioning, cumbersome shielding, and low loading and unloading efficiency in the prior art.
