[0002] In the field of electronics, a very important step in the manufacturing process of semiconductor chips is chip mounting. The principle of chip mounting is to connect the chip and the substrate together. The chip and the substrate cannot be connected directly, and a medium needs to be added in the middle to connect them. This medium is the mounting glue (silver glue); the mounting glue is stored in a tube, and the air pressure is increased on it through the bottom glue head, and dots (or drawings) are placed on the substrate. The chip is placed on the glue to form a connection.

[0003] The Chinese patent document with the existing announcement number CN216459757U discloses an automatic glue dispensing machine, which belongs to the field of glue dispensing equipment. The automatic glue dispensing machine includes a glue dispensing base, and also includes: a support platform fixedly connected to the outer wall of the glue dispensing base; a fixture connected to the top wall of the glue dispensing base; a clamping mechanism connected to the top wall of the glue dispensing base, the clamping mechanism includes a slide, a push plate assembly and a rotating assembly, the slide is fixedly connected to the top wall of the glue dispensing base, the rotating assembly is connected to the outer wall of the slide, the buffer device is fixedly connected to the top wall of the glue dispensing base, the inner wall of the connecting bracket is connected to the glue dispensing device, the outer wall of the connecting bracket is connected to the clamping mechanism, and the output end of the clamping mechanism cooperates with the glue dispensing device; the utility model has a simple structure and is easy to operate, and the corresponding fixture can be quickly replaced to realize the glue dispensing operation of products of different specifications. At the same time, the length of the glue dispensing device can be adjusted to adapt to different fixtures, thereby improving production efficiency and practicality.

[0004] However, in the above scheme and the prior art, as the mounting glue dots onto the substrate, the mounting glue will continue to decrease, and a large amount of air will be mixed in the final colloid, resulting in voids at the bottom of the chip and causing the product to be scrapped. Currently, a line is drawn at the bottom of the hose with a pen. When it is below this line, the glue is not in use. During the operation, production personnel need to observe frequently, which is inconvenient. One negligence may result in the glue being used up and not replaced in time, resulting in defective products. Utility Model Content

After the loading hose 4 is connected to the rubber head 5 and the air pipe 6, the loading hose 4 is placed obliquely in the first support frame 8 and the second support frame 11, and the semi-ring block 13 is rotated to fix the position of the loading hose 4. The weight sensing device 3 detects the weight of the film rubber in the loading hose 4 in real time and sets a value for the weight of the loading rubber. After the weight sensing device 3 detects that the weight of the film rubber in the loading hose 4 reaches this value, the machine automatically alarms, and the personnel replace the loading hose 4 when they hear the alarm.

[0024] Embodiment 2, based on embodiment 1:

[0025] The positioning column 7 in the placement component is symmetrically fixedly arranged on the rubber head 5, and the first support frame 8 and the second support frame 11 are fixedly arranged on the upper end of the weight sensing device 3; a first arc groove 9 is opened at the end of the first support frame 8, and a positioning groove 10 is symmetrically opened on the side wall of the first arc groove 9, and a second arc groove 12 is opened at the end of the second support frame 11; the semi-ring block 13 is hingedly arranged at the side end of the second support frame 11, and a clamping block 14 is fixedly arranged on the side wall of the semi-ring block 13, and the clamping groove 15 is opened on the side wall of the second support frame 11; the positioning column 7 corresponds to the positioning groove 10 in the setting position and the same number of settings, and the two are clamped; the clamping block 14 corresponds to the clamping groove 15 in the setting position and the same number of settings, and the two are clamped; the first arc groove 9 is clamped with the rubber head 5, the second arc groove 12 is clamped with the film loading hose 4, the annular groove of the semi-ring block 13 is clamped with the film loading hose 4, and the side wall of the semi-ring block 13 is clamped with the end wall of the second support frame 11.

[0026] When in use, after the loading hose 4, the rubber head 5 and the air pipe 6 are set, the rubber head 5 is clamped in the first arc groove 9 and the positioning column 7 is clamped in the positioning groove 10 to prevent the rubber head 5 from rotating during the dispensing process. At the same time, the loading hose 4 is clamped in the second arc groove 12, and then the semi-ring block 13 is rotated so that its ring groove is clamped with the loading hose 4. At this time, the side wall of the semi-ring block 13 is clamped with the end wall of the second support frame 11, and the clamping block 14 is clamped with the clamping groove 15. Then, the position of the semi-ring block 13 is fixed and then the position of the loading hose 4 is fixed, so that the loading hose 4 is stably installed on the weight sensing device 3.

[0027] The remaining technical features and technical effects of this embodiment are the same as those of the first embodiment.

[0028] Embodiment 3, based on embodiment 2:

[0030] When in use, during the process of rotating the semi-ring block 13, the convex plate 19 is pushed downward along the slide groove 18, so that the plug post 20 moves downward and retracts into the square groove 17. During the process, the spring 21 is compressed to ensure that the block 14 is smoothly engaged in the slot 15. Then the convex plate 19 is released, and the spring 21 is reset to push the convex plate 19 to move upward, so that the plug post 20 is inserted into the slide groove 18, thereby fixing the position of the semi-ring block 13 and ensuring the stable installation of the loading hose 4.

[0031] The remaining technical features and technical effects of this embodiment are the same as those of the second embodiment.
