Abstract
Description
Technical Field
[0001] This utility model relates to a dispensing device, specifically to a device for adjusting the horizontal level of the end face of a dispensing head. Background Technology
[0002] In the field of 3C display modules such as mobile phones, the market demand for ultra-narrow bezels in mobile phones and displays is becoming increasingly stringent. Traditional bonding and bending processes are no longer sufficient to meet the requirements for ultra-narrow bezels, and SideWrapping technology is gradually becoming a new technological direction. This process eliminates the need for bending and mainly connects the electronic circuits on both sides through dispensing, which can significantly reduce the size of the bottom bezel of the mobile phone.
[0003] However, traditional dispensing has many problems in the SideWrapping process: First, it has poor stability, and even small fluctuations in dispensing height can significantly affect the circuit bonding effect; second, it is slow, and as the number of circuits increases, the speed of traditional dispensing can no longer meet the production capacity requirements; third, it is inefficient, because the stability of ordinary dispensing is not good, it is difficult to combine it into a multi-needle dispensing method, which leads to low overall efficiency.
[0004] To address these issues, electrically assisted dispensing technology was developed. However, in practical applications, it has been found that even slight differences in the parallelism between the dispensing needle tip and the dispensing plane can cause variations in the dispensing position, resulting in discontinuous glue lines and other problems that severely affect dispensing quality and product performance.
[0005] Therefore, there is an urgent need for a device that can effectively adjust the level of the dispensing head end face. Utility Model Content
[0006] The purpose of this invention is to provide a device for adjusting the horizontal level of the end face of a dispensing head, so as to solve the dispensing quality problem caused by poor parallelism between the needle end face and the dispensing plane in existing electrically assisted dispensing.
[0007] To solve the above technical problems, this utility model provides the following solution: A horizontal adjustment device for the end face of a dispensing head, comprising:
[0008] The first rotary differential platform is set along the first direction;
[0009] A second rotary differential platform is provided along a second direction and is mounted on a first rotary portion of the first rotary differential platform. The second direction is perpendicular to the first direction, and the second rotary differential platform has a second rotary portion.
[0010] The needle mounting module is fixed to the second rotating part.
[0011] Furthermore, the first rotating differential platform and the second rotating differential platform have the same structure.
[0012] Furthermore, the first rotary differential platform has a fine-tuning handle and a turntable driven by the fine-tuning handle, and the second rotary differential platform is vertically mounted on the turntable of the first rotary differential platform.
[0013] Furthermore, the needle mounting module is mounted on the turntable of the second rotary differential platform.
[0014] Furthermore, the needle mounting module has a slide and a slider, with the slide fixed to the turntable of the second rotary differential platform;
[0015] The slide block is provided with a slide groove, and the bottom surface of the slide groove is provided with multiple linearly distributed threaded holes;
[0016] The slider slides into the groove, and its outer plate surface is provided with at least two positioning posts and multiple mounting holes.
[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting up a first and a second mutually perpendicular rotary differential platform, this utility model can precisely rotate and adjust the needle mounting module in two mutually perpendicular directions, thereby achieving fine adjustment of the needle end face level. This effectively improves the parallelism between the dispensing needle end face and the dispensing plane, reduces problems such as dispensing position variation and discontinuous glue lines, and improves dispensing quality and product performance.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present utility model. Obviously, the embodiments described in this utility model 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0023] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0024] Example 1: The specific structure of this utility model is as follows:
[0025] Please refer to the appendix. Figure 1-3 The present invention provides a device for adjusting the end face level of a dispensing head, comprising:
[0026] The first rotary differential platform 1 is set along the first direction;
[0027] A second rotating differential platform 2 is arranged along a second direction and is mounted on the first rotating part of the first rotating differential platform 1. The second direction is perpendicular to the first direction, and the second rotating differential platform 2 has a second rotating part.
[0028] Needle mounting module 9 is fixed to the second rotating part.
[0029] The first rotating differentiating platform 1 and the second rotating differentiating platform 2 have the same structure. The following description focuses only on the structure of the first rotating differentiating platform 1.
[0030] The first rotary differential platform 1 has a fine-tuning handle and a turntable driven by the fine-tuning handle. The second rotary differential platform 2 is vertically mounted on the turntable of the first rotary differential platform 1. Rotating the handle of the first rotary differential platform 1 drives the turntable of the first rotary differential platform 1 to rotate, which in turn drives the second rotary differential platform 2 to rotate synchronously.
[0031] The needle mounting module 9 is mounted on the turntable of the second rotary differential platform 2, and the needle mounting module 9 rotates synchronously with the turntable of the second rotary differential platform 2.
[0032] The needle mounting module 9 has a slide 91 and a slider 92, with the slide 91 fixed to the turntable of the second rotary differential platform 2;
[0033] The slide block 91 is provided with a slide groove, and the bottom surface of the slide groove is provided with a plurality of linearly distributed threaded holes;
[0034] The slider 92 is slidably connected to the groove, and its outer plate surface is provided with at least two positioning posts 93 and multiple mounting holes 94.
[0035] The needle assembly 3 is mounted on the slider 92 and fixed with screws. It includes a mounting plate that is mounted on the slider 92. The upper part of the mounting plate is mounted with a syringe 7, and the lower part is mounted with a needle through a needle positioning part 5. The needle and the dispensing end of the syringe 7 are connected.
[0036] like Figure 1 As shown, the first rotating differential platform 1 is mounted on a vertical plate, which is fixed to a rear plate in a height-adjustable manner. A clearance opening is provided on one side of the vertical plate. In the clearance opening area, a CCD module 8 is mounted on the rear plate. The CCD module 8 is used to take pictures and align the pins, so as to achieve the purpose of fine adjustment of the pins.
[0037] like Figure 1 As shown, the vertical plate 6 is equipped with a needle alignment assembly. When the dispensing needle is changed at the beginning or during dispensing, the parallelism between the end face and the dispensing surface needs to be corrected. This utility model module is installed on the dispensing Z-axis. After the needle alignment is started, the module automatically runs to the needle alignment module. The CCD module 8 takes a picture and provides the needle position. Based on the returned parameters, the technician manually corrects the differential heads of the first rotary differential platform 1 and the second rotary differential platform 2. After adjustment, the position is locked and the machine is started for dispensing.
[0038] In summary, this invention, by setting up a first and a second mutually perpendicular rotary differential platform, enables precise rotational adjustment of the needle mounting module in two mutually perpendicular directions. This allows for fine adjustment of the needle tip's horizontal level, effectively improving the parallelism between the dispensing needle tip's end face and the dispensing plane, reducing problems such as dispensing position variations and discontinuous glue lines, and enhancing dispensing quality. The sliding block and slider structure of the needle mounting module allows for flexible adjustment of the needle's mounting position, enhancing the device's applicability and flexibility. The identical structure of the two rotary differential platforms facilitates manufacturing, installation, and maintenance, reducing production costs and ease of use.
[0039] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the contents of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
