Description

Technical Field

[0001] The utility model belongs to the technical field of glue dispensing head detection equipment, and particularly relates to a glue dispensing head detection device. Background Art

[0002] Glue dispensing inspection during the chip pressure-holding process is primarily used to ensure accuracy and reliability during chip production. The main steps of glue dispensing inspection include: 1. Glue quantity inspection: Using image processing technology, the glue quantity on the chip is measured to ensure that the glue quantity meets production standards. 2. Glue point position inspection: The glue point position on the chip is inspected to ensure that the glue point is accurately positioned.

[0003] Currently, during the production process, there is no real-time monitoring of the dispensing process. Only basic dispensing actions and necessary calibration procedures are performed, but the actual dispensing status cannot be monitored and recorded. When dispensing failure occurs, the cause cannot be traced.

[0004] In the Chinese patent application publication number CN116550557A, a chip surface dispensing device for chip detection is disclosed, which includes a dispensing mechanism arranged on the surface of the base, and the dispensing mechanism includes a dispensing component, an adjustment component, a quantity control component and a replacement component. The dispensing component is arranged above the base, and the adjustment component is arranged on the surface of the dispensing component. However, during the dispensing process, the video of the dispensing cannot be effectively recorded. Therefore, when a batch of dispensing problems occurs, it is difficult to find the problem in the product packaging link, and they need to be discharged one by one, which greatly affects the packaging efficiency.

[0032] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0033] like Figure 1 、 Figure 2 As shown, the embodiment of the present invention provides a dispensing head detection device, including a dispensing device body 1, a fixing seat 2, and a detection component 3.

[0034] The side of the glue dispenser body 1 is connected to the positioning plate 4 through the fixing seat 2; at this time, the fixing seat 2 is an L-shaped structure as a whole, and a first limit block 201 is provided at the bottom of the L-shaped structure of the fixing seat 2, and a horizontal V-shaped groove 202 is provided at the bending part of the L-shaped structure of the fixing seat 2. The V-shaped groove 202 forms a side clamp for the glue dispensing head 11 extending in the vertical direction of the glue dispenser body 1, ensuring the stable output of the glue dispensing head 11 during the entire glue dispensing process, and no relative slippage occurs.

[0035] The positioning plate 4 is an L-shaped structure, the bottom of which is horizontally bent, and an opening 401 is provided at the bend that runs through the vertical direction, so that the opening 401 forms a clamping and fixing of the front end of the bottom dispensing head 11 extending in the vertical direction of the dispensing device body 1; at the same time, a second limiting block 402 is provided on the upper part of the L-shaped structure of the positioning plate 4, so that when the fixing seat 2 is fixed above the positioning plate 4, a bearing gap is formed between the first limiting block 201 and the second limiting block 402, which is used to fix the dispensing head 11 in the vertical direction. Of course, the relative spacing between the fixing seat 2 and the positioning plate 4 can be adjusted according to the model size of the dispensing head 11. The dispensing head 11 of the dispensing device body 1 is located as a whole in the gap between the L-shaped structure of the fixing seat 2 and the L-shaped structure of the positioning plate 4, so as to form a component that accommodates and fixes the dispensing head 11 of the dispensing device body 1.

[0036] The fixing base 2 is provided with through slots 203 on both vertical sides. Bolts are passed through the slots 203 to secure the fixing base 2 to the front end of the positioning plate 4. The lateral spacing between the two sets of slots 203 is greater than the lateral width of the glue dispenser body 1. That is, when the glue dispenser body 1 and the fixing base 2 are relatively fixed, the locking of the slots 203 will not be affected.

[0037] A fixing plate 5 is provided on the rear end face where the positioning plate 4 is located, and locking holes 501 are provided on the fixing plate 5 that penetrate the entire end face and are distributed in an array;

[0038] The bolts are passed through the grooves 203 where the fixing seat 2 is located, and are locked and fixed with the corresponding locking holes 501 on the rear end surface fixing plate 5 , thereby simultaneously locking the positioning plate 4 .

[0039] The locking hole 501 can also be connected to the equipment body, and the opening of the locking hole 501 can reduce the load of the entire dispensing head detection device without affecting its structural strength. At the same time, according to the change of the setting position, the locking hole 501 at the appropriate position can be selected for fixation.

[0040] The detection assembly 3 is located at the bottom of the rear end face of the fixing base 2 (which can be set at the rear end of the fixing plate 5). The front end of the detection assembly 3 captures and records the glue discharge position of the dispensing head at the bottom of the dispenser body 1. The detection assembly 3 includes a detection camera 31 and a deflection seat 32. The deflection seat 32 is fixed to the bottom of the rear end face of the fixing base 2. Connection holes 301 are opened on both sides of the deflection seat 32.

[0041] The connection hole 301 is used to achieve relative fixation of the detection camera 31 and the deflection seat 32 by bolts.

[0042] The connection hole 301 is a waist-shaped hole structure. In this case, the waist-shaped hole can remove excess material while meeting the structural strength requirements, thereby reducing the weight of the part. The waist-shaped hole can also be used as a prestressed hole, improving the reliability and load-bearing capacity of the connection in fastener connections such as bolt connections. The detection camera 31 is located in the gap between the deflection seats 32, and at the same time passes through the connection hole 301 and is connected to the detection camera 31. By adjusting the deflection angle between the detection camera 31 and the connection hole 301, the monitoring angle of the detection camera 31 can be adjusted to meet the changes in the dispensing position of different models of dispensing heads 11, and the operation can be changed at any time.

[0043] When dispensing glue, the specific usage process of the detection camera 31 is as follows: the dispensing head 11 moves with the fixed equipment to dispense glue at the position where the product is to be dispensed. Before dispensing glue, the detection camera 31 is turned on and the focus is on the center of the needle of the dispensing head 11. The dispensing trajectory is recorded with the needle of the dispensing head 11 as the reference and uploaded to the control center of the equipment in real time. Therefore, the recorded video can accurately find the defects in the dispensing process and make corrections and modifications in real time.

[0044] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention as claimed.
