[0002] Glue dispenser is a device used to precisely control the application of liquid glue on workpieces. It is commonly used in industries such as electronic assembly, circuit board packaging, automotive parts manufacturing, and medical device manufacturing.

[0003] During the production process of the temperature sensor, precise glue dispensing is required on the connection parts between the terminals and the wires. The automated glue dispensing machine can ensure that the glue is evenly applied to the connection parts between the temperature sensor terminals and the wires, making the connection between the wires and the terminals more reliable.

[0004] When dispensing glue, it is necessary to dispense glue on both sides of the wire respectively, but the existing dispensing machine has only one glue needle, which leads to slow dispensing efficiency, and the bending of the wire can easily hinder the dispensing. Therefore, we propose a terminal wire dispensing device for temperature sensors. Utility Model Content

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0027] Example: Refer to Figures 1-8 A terminal wire dispensing device for a temperature sensor comprises a lateral moving mechanism 2 arranged on a base 1 and a vertical moving mechanism 3 installed on the lateral moving mechanism 2, and further comprises: a mounting frame 4, which is installed on the vertical moving mechanism 3, and the mounting frame 4 is respectively provided with a first dispensing needle 41 and a second dispensing needle 42, and the dispensing ends of the first dispensing needle 41 and the second dispensing needle 42 are arranged opposite to each other; a long jig 5 connected to the base 1, and a plurality of placement grooves 51 are opened on the long jig 5 at equal intervals, and the inner walls on both sides of the placement groove 51 are slidably connected with clamping blocks 52, when the first dispensing needle 41 and the second dispensing needle 42 pass through the long jig 5, the clamping blocks 52 are pushed to slide into the placement groove 51 in linkage, so as to further clamp the terminal in the placement groove 51; a placement plate 56, which is located above the long jig 5, and is used to place the wire;

[0028] The mounting bracket 4 is symmetrically and fixedly connected with connecting arms 44. One ends of the two connecting arms 44 are opposite to each other, and rubber blocks 43 are fixedly connected to the connecting arms 44. The outer side surface of the clamping block 52 is provided with an inclined groove wall 53, and the rubber block 43 corresponds to the inclined groove wall 53;

[0029] On the outer sides of the two clamping blocks 52 in the placing groove 51, connecting plates 54 are fixedly connected respectively. The two connecting plates 54 are fixedly connected to each other through a spring 55;

[0030] The placing plate 56 is installed on the long strip jig 5 through a connecting rod. The width of the connecting rod is smaller than the distance between the first dispensing needle 41 and the second dispensing needle 42;

[0031] On the placing plate 56, snap boxes 50 corresponding to a plurality of placing grooves 51 are fixedly connected respectively, for clamping the temperature sensor;

[0032] On the bottom surface of the placing plate 56, a plurality of fixing frames 59 corresponding to the snap boxes 50 are fixedly connected. On the fixing frames 59, a first winding cylinder 57 and a second winding cylinder 58 are fixedly connected respectively, for winding the wire;

[0033] The first winding cylinder 57 and the second winding cylinder 58 are staggered;

[0034] On the base 1, a movable connecting platform 11 is arranged. On the long strip jig 5, a bottom plate is fixedly connected. The bottom plate is connected with the movable connecting platform 11;

[0035] When the device is in use, by inserting the terminal into the placing groove 51 and making the wire part upward, then winding the wire part around the staggered first winding cylinder 57 and second winding cylinder 58, so that the part of the wire that is too long is wound around the first winding cylinder 57 and the second winding cylinder 58. Then, the shell of the temperature sensor is buckled into the snap box 50 for fixation, so that the wire part and the terminal are perpendicular, thus effectively avoiding the wire bending and blocking the subsequent dispensing operation;

[0036] When dispensing, the horizontal moving mechanism 2 drives the vertical moving mechanism 3 to translate. The vertical moving mechanism 3 can drive the mounting bracket 4 to move up and down, so that the first dispensing needle 41 and the second dispensing needle 42 are accurately aligned with both sides of the connection between the terminal and the wire. By driving the vertical moving mechanism 3 to translate through the horizontal moving mechanism 2, the first dispensing needle 41 and the second dispensing needle 42 located on both sides of the terminal can simultaneously perform dispensing and smear between the terminal and the wire;

[0037] In order to further improve the accuracy of glue dispensing and to facilitate the insertion of the terminal into the placement groove 51, the present device is provided with a clamping block 52 which is slidably arranged on both sides of the placement groove 51. When the first glue dispensing needle 41 and the second glue dispensing needle 42 are performing glue dispensing, the rubber block 43 on the connecting arm 44 will first contact the inclined groove wall 53 of the clamping block 52 and push the clamping block 52 to slide into the placement groove 51. During the glue dispensing operation, the rubber block 43 on the connecting arm 44 can further clamp the terminals to be glued one by one, thereby preventing the terminals from shaking during the glue dispensing process, which would cause a decrease in the glue dispensing quality.

[0038] The lateral moving mechanism 2, the vertical moving mechanism 3, and the mobile connecting platform 11 are all connected to the corresponding synchronous belt through a set motor, symmetrically rotating synchronous wheels, and a synchronous belt connected between the two synchronous wheels, and then through a correspondingly set mounting plate. The synchronous wheel is driven by the motor to rotate, so that the synchronous belt rotates, and then the corresponding mounting plate is driven to move, thereby realizing lateral movement, vertical movement, and forward and backward movement of the mobile connecting platform 11, and then the lateral moving mechanism 2, the vertical moving mechanism 3, and the mobile connecting platform 11 are used to realize movement in three directions to meet the needs of dispensing glue on terminals and wires.

[0039] Therefore, the utility model can simultaneously dispense glue on both sides of the terminal and the wire connection by setting the first dispensing needle 41 and the second dispensing needle 42 located on both sides of the terminal, thereby improving the dispensing efficiency. At the same time, by setting the high and low long strip fixture 5 and the placement plate 56, the temperature sensor with the terminal and the wire is fixed, so that the terminal and the wire are in a vertical state, thereby effectively avoiding the bending of the wire and blocking the dispensing operation, thereby effectively improving the dispensing quality. At the same time, when dispensing glue on the terminals and wires in the placement groove 51 one by one, the clamping block 52 can be pushed in conjunction to pre-clamp the terminals in the placement groove 51, further avoiding the shaking of the terminals during the dispensing process one by one.

Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with the present invention can make some changes or modifications to equivalent embodiments of equivalent changes using the above-mentioned technical contents without departing from the scope of the technical solution of the present invention. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the present invention.
