Description

Technical Field

[0001] This utility model relates to the field of precision manufacturing and automated processing technology of mobile phone parts, and in particular to a mobile phone processing adhesive dispensing fixture. Background Technology

[0002] In the smartphone manufacturing process, the dispensing process is one of the key steps. It is mainly used for sealing and bonding the phone casing to the mid-frame, fixing the screen touch layer to the display layer, and shockproof bonding of the camera module to the motherboard. This process has extremely high requirements for the accuracy of the glue application position, the uniformity of the glue layer thickness, and the stability of the glue's morphology before curing. If the component positioning is off during the dispensing process, it is easy for the glue to overflow and contaminate functional areas (such as the earpiece and button holes). If the component is not fixed stably and shakes, it will cause the glue layer to break or accumulate locally, which will directly affect the assembly accuracy and service life of the phone components, and may even cause quality problems such as screen detachment and water ingress in the casing during later use. Chinese Patent Publication No. CN217289106U discloses a dispensing fixture for mobile phone processing, relating to the field of mobile phone processing technology. It includes a base plate, with a rectangular buffer mechanism fixedly installed at each of the four corners of the base plate's upper surface. A rectangular box is installed between the opposing sides of the buffer mechanism. A miniature vibration motor is fixedly installed on the lower surface of the rectangular box. A partition is fixedly installed between the inner walls of the rectangular box, dividing the rectangular box from bottom to top into a cooling chamber and a placement chamber. Semiconductor cooling chips are embedded on the front and rear side walls of the rectangular box corresponding to the cooling chamber. An air distribution mechanism is provided on the front side of the rectangular box corresponding to the cooling chamber, and a material ejection mechanism is provided on the lower side wall of the rectangular box. This utility model adds a vibration function, causing the glue to vibrate after dispensing, preventing a vacuum in the glue, improving the bonding quality of subsequent electrical components, facilitating the removal of the mobile phone motherboard, accelerating glue solidification, and improving production efficiency. The aforementioned patent documents still have the following defects in practice: When picking up materials, the rectangular box needs to be pressed down manually so that the top rod of the spring mechanism contacts the bottom plate, and then the main board is lifted by the top block. This operation requires manual application of external force, and the pressing force is difficult to control. If the pressing force is too small, the top block cannot fully lift the main board, making it difficult to pick up materials. If the pressing force is too large, it will cause the spring of the buffer mechanism to be over-compressed, which may not only damage the spring, but also cause the main board to be subjected to excessive impact force, resulting in deformation of the main board or component falling off. Summary of the Invention

[0003] The main purpose of this utility model is to provide a mobile phone processing adhesive dispensing fixture, which can effectively solve the problems mentioned above.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A mobile phone processing adhesive dispensing fixture includes a base, a transmission mechanism in the middle of the base, a fixing mechanism on the upper part of the transmission mechanism, a support mechanism on the upper part of the base, and two vibration mechanisms in the middle of the support mechanism.

[0005] Preferably, the transmission mechanism includes a hydraulic cylinder, the output end of which is provided with a fixed rod, and the upper part of the fixed rod is provided with a concave frame.

[0006] Preferably, the fixing mechanism includes a U-shaped platform, the lower part of which is disposed on the upper part of the concave frame, a limiting frame is provided at the lower part of the U-shaped platform, four fixing blocks are provided in the middle of the U-shaped platform, and two racks are provided in the middle of the U-shaped platform.

[0007] Preferably, the support mechanism includes a support plate, the lower part of which is disposed on the upper part of the base, two springs are provided on the upper part of the support plate, a telescopic sleeve is provided in the middle of the support plate, a telescopic rod is provided inside the telescopic sleeve, a fixed plate is provided on the upper part of the telescopic rod, and two transmission rods are provided on the lower part of the fixed plate.

[0008] Preferably, the vibration mechanism includes a first support frame, the lower part of which is disposed on the upper part of a support plate, the upper part of which is provided with a cam, the front part of which is provided with a connecting rod, the front part of which is provided with a gear, and the gear is provided with a second support frame, the lower part of which is disposed on the upper part of the support plate.

[0009] Preferably, the two racks mesh with two gears respectively.

[0010] Preferably, the cam has three protrusions, and two of the cams are located directly below the two fixed plates.

[0011] Compared with the prior art, the present invention has the following beneficial effects: In this embodiment, the vibration mechanism, through a rack-pinion-cam transmission structure, can drive the fixing plate to produce subtle and regular up-and-down vibrations during the downward movement of the fixing mechanism. This vibration can expel air bubbles from the glue after application, preventing the formation of vacuum gaps after the glue cures, significantly improving the bonding strength between components, reducing quality risks such as screen detachment and water ingress in the casing during later use, and ensuring the uniformity of the glue layer thickness, which meets the process requirements of precision mobile phone manufacturing. In this embodiment, the hydraulic cylinder of the transmission mechanism drives the fixing rod and concave frame to move down, directly causing the fixing mechanism to detach from the fixing plate, so that the mobile phone components are naturally exposed. No external force needs to be applied manually, which completely solves the problem of "difficulty in controlling the pressing pressure". It avoids the difficulty in picking up materials caused by insufficient pressing pressure, and also prevents the loss caused by excessive compression of springs, deformation of motherboard or component falling off due to excessive pressing pressure.

[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0015] Example 1, as Figure 1 - Figure 2 As shown, a mobile phone processing dispensing fixture includes a base 1, a transmission mechanism 2 in the middle of the base 1, a fixing mechanism 3 on the upper part of the transmission mechanism 2, a support mechanism 4 on the upper part of the base 1, and two vibration mechanisms 5 in the middle of the support mechanism 4. In this embodiment, the mobile phone component is precisely embedded in the groove formed by the support mechanism 4 and the fixing mechanism 3. Adhesive is applied to the mobile phone component. After the adhesive is applied, the transmission mechanism 2 is activated. The transmission mechanism 2 drives the fixing mechanism 3 to move downward to expose the mobile phone component, making it easier to replace the mobile phone component. At the same time, when the fixing mechanism 3 moves downward, it drives the support mechanism 4 to vibrate through the vibration mechanism 5. The support mechanism 4 drives the component to vibrate, causing the mobile phone component after adhesive application to vibrate, avoiding a vacuum in the adhesive and making subsequent components better bonded. To move the fixed mechanism 3, see [reference] Figure 3 The transmission mechanism 2 includes a hydraulic cylinder 21, and a fixed rod 22 is provided at the output end of the hydraulic cylinder 21. A concave frame 23 is provided on the upper part of the fixed rod 22. During implementation, hydraulic cylinder 21 is activated, and hydraulic cylinder 21 drives concave frame 23 to move downward through fixed rod 22. Concave frame 23 drives fixed mechanism 3 to move downward.

[0016] Example 2: To facilitate the replacement of mobile phone components and simultaneously cause the mobile phone components to vibrate, see [reference needed]. Figure 3 The fixing mechanism 3 includes a U-shaped platform 31, the lower part of which is set on the upper part of the concave frame 23. A limiting frame 32 is provided at the lower part of the U-shaped platform 31. Four fixing blocks 33 are provided in the middle of the U-shaped platform 31. Two racks 34 are provided in the middle of the U-shaped platform 31. During implementation, the concave frame 23 drives the U-shaped table 31 to move downward, and the U-shaped table 31 drives the limiting frame 32 to move downward along the outer surface of the base 1. The limiting frame 32 limits the movement direction of the fixing mechanism 3. The limiting frame 32 drives the fixing block 33 and the rack 34 to move downward. The rack 34 cooperates with the vibration mechanism 5 to drive the fixing plate 45 to vibrate. When the fixing block 33 is at the highest point, it supports the fixing plate 45 to prevent the fixing plate 45 from shaking during dispensing and affecting the dispensing effect. For further details, please refer to [link / reference]. Figure 4 The support mechanism 4 includes a support plate 41. The lower part of the support plate 41 is set on the upper part of the base 1. Two springs 42 are provided on the upper part of the support plate 41. A telescopic sleeve 43 is provided in the middle of the support plate 41. A telescopic rod 44 is provided inside the telescopic sleeve 43. A fixed plate 45 is provided on the upper part of the telescopic rod 44. Two transmission rods 46 are provided on the lower part of the fixed plate 45. During implementation, the support plate 41 is fixed on the upper part of the base 1. When the fixing block 33 is at its highest position, it supports the fixing plate 45. The spring 42 is slightly stretched to fix the fixing plate 45 on the fixing block 33 to prevent the fixing plate 45 from shaking. The vibration mechanism 5 and the transmission rod 46 work together to drive the fixing plate 45 to shake. The telescopic rod 44 ensures that the fixing plate 45 vibrates up and down to prevent the glue from spreading to the left and right. The spring 42 supports the fixing plate 45 and pulls the fixing plate 45 to vibrate up and down. For further details, please refer to [link / reference]. Figure 5 The vibration mechanism 5 includes a support frame 51, the lower part of which is set on the upper part of the support plate 41. A cam 52 is provided on the upper part of the support frame 51. A connecting rod 53 is provided in front of the cam 52. A gear 54 is provided in front of the connecting rod 53. A support frame 55 is provided inside the gear 54. The lower part of the support frame 55 is set on the upper part of the support plate 41. The two gears 54 mesh with two racks 34 respectively. The cam 52 has three protrusions. The two cams 52 are located directly below the two fixed plates 45 respectively. During implementation, when the rack 34 moves downward, it drives the gear 54 to rotate. The gear 54 drives the cam 52 to rotate through the connecting rod 53. The protruding part of the cam 52 lifts the transmission rod 46 and the fixed plate 45. When it moves away, the transmission rod 46 and the fixed plate 45 fall back under the action of the spring 42, causing the fixed plate 45 to vibrate slightly. The first support frame 51 and the second support frame 55 support the cam 52 and the gear 54.
