Description

Technical Field

[0001] The utility model belongs to the technical field of ultrasonic welding devices, and in particular relates to an ultrasonic welding device for a temperature sensor. Background Art

[0002] Ultrasonic welding uses high-frequency vibration waves to transmit to the surfaces of two objects to be welded. Under pressure, the two surfaces of the objects rub against each other to form a fusion between the molecular layers.

[0003] In the production process of temperature sensors, one of the steps is to connect the wires to the plates. Ultrasonic welding can improve the welding quality, but the existing welding process is done manually. When welding manually, the plate needs to be placed on the welding table first, and then one end of the wire is brought into contact with the plate. Then, the welding head of the ultrasonic welding machine is lowered to achieve ultrasonic welding of the plate and the wire. However, this method reduces the welding efficiency, and without the assistance of additional tools, fatigue easily occurs during the welding operation. For this reason, we propose an ultrasonic welding device for temperature sensors. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide an ultrasonic welding device for a temperature sensor which can overcome the above problems or at least partially solve the above problems.

[0005] In order to solve the above technical problems, the basic concept of the technical solution adopted by the utility model is: an ultrasonic welding device for a temperature sensor, including a mounting frame with a welding machine installed, and also including: a connecting plate arranged on the mounting frame, a first synchronous belt and a second synchronous belt are rotatably arranged on the connecting plate, and a channel is formed between the first synchronous belt and the second synchronous belt; a first placement plate and a second placement plate are respectively circumferentially connected to the first synchronous belt and the second synchronous belt, and a plate is located between the first placement plate and the second placement plate; a base block is installed on the connecting plate, and the base block is located in the channel; a jig connected to the base block through a connecting arm, and the jig is located below the ultrasonic welding head, and when the first placement plate and the second placement plate drive the plate to pass through the jig, the plate is located between the jig and the base block.

[0006] Preferably, it also includes a first bracket and a second bracket, the first placement plate is connected to the first bracket, the first bracket is installed on the first synchronous belt, the second placement plate is connected to the second bracket, and the second bracket is installed on the second synchronous belt.

[0007] Furthermore, the second placement plate is installed on the left side of the second bracket.

[0008] Preferably, the fixture includes a long rod, one side of which is respectively fixedly connected with a first short rod and a second short rod, a welding space is formed between the long rod, the first short rod and the second short rod, and when the first placing plate and the second placing plate drive the plate to move below the welding space, the long rod, the first short rod and the second short rod are used to limit the two ends of the plate.

[0009] Furthermore, a placement opening is formed between the first short rod and the second short rod.

[0010] Furthermore, an alignment mark is provided on the upper surface of the long bar, and one end of the alignment mark passes through the long bar near the welding position.

[0011] Furthermore, a guide plate is installed at one end of the mounting frame located at the first synchronous belt and the second synchronous belt.

[0012] Furthermore, the mounting frame is symmetrically fixedly connected with a slide rail, the slide rail is slidably connected with a slide seat, the connecting plate is connected to the slide seat, and a locking bolt is threadedly connected to one side of the slide seat.

[0013] After adopting the above technical solution, the utility model has the following beneficial effects compared with the prior art: the utility model can further assist the operator in welding when ultrasonic welding the wire and the plate by means of the set fixture, thereby reducing the operator fatigue and improving the work efficiency, and when the plate is placed on the first placement plate and the second placement plate continuously, the ultrasonic welding efficiency can be further improved;

[0014] The device is provided with a jig. When the plate moves below the ultrasonic welding head, the plate is located below the jig, that is, below the long bar, the first short bar, and the second short bar. The welding space just corresponds to the ultrasonic welding head. The placement opening is provided for positioning. The operator can quickly place the wire on the plate, and one end of the wire can be located in the middle of the plate, thereby improving the welding quality.

[0015] When the ultrasonic welding head rises, the plates and wires stuck to the ultrasonic welding head will rise with the ultrasonic welding head, and will be blocked by the long rod, the first short rod, and the second short rod, and fall back to the first placement plate and the second placement plate. This makes the first synchronous belt and the second synchronous belt rotate and bring the welded plates and wires to one side, so that the welded plates and wires can slide smoothly from the first placement plate and the second placement plate.

[0016] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] 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.

[0026] Example: Refer to Figure 1-Figure 6, an ultrasonic welding device for a temperature sensor, comprising a mounting frame 1 with a welding machine 2 installed, and also comprising: a connecting plate 112 arranged on the mounting frame 1, on which a first synchronous belt 113 and a second synchronous belt 114 are respectively rotatably arranged, and a channel 4 is formed between the first synchronous belt 113 and the second synchronous belt 114; a first placement plate 121 and a second placement plate 131 are respectively circumferentially connected to the first synchronous belt 113 and the second synchronous belt 114, and a plate 3 is located between the first placement plate 121 and the second placement plate 131; a base block 15, which is installed on the connecting plate 112, and the base block 15 is located in the channel 4; a jig 14 connected to the base block 15 through a connecting arm 140, and the jig 14 is located below the ultrasonic welding head 21, and when the first placement plate 121 and the second placement plate 131 drive the plate 3 to pass through the jig 14, the plate 3 is in the position between the jig 14 and the base block 15; it also includes a first bracket 12 and a second bracket 13, a first placement plate 121 is connected to the first bracket 12, the first bracket 12 is installed on the first synchronous belt 113, the second placement plate 131 is connected to the second bracket 13, and the second bracket 13 is installed on the second synchronous belt 114; the jig 14 includes a long bar 141, one side of the long bar 141 is respectively fixedly connected with a first short bar 142 and a second short bar 143, a welding space 145 is formed between the long bar 141, the first short bar 142, and the second short bar 143, when the first placement plate 121 and the second placement plate 131 drive the plate 3 to move below the welding space 145, the long bar 141, the first short bar 142, and the second short bar 143 are used to limit the two ends of the plate 3; a placement opening 144 is formed between the first short bar 142 and the second short bar 143;

[0027] When the device is in use, the plate 3 is placed between the first placement plate 121 and the second placement plate 131, and then the first synchronous belt 113 and the second synchronous belt 114 are driven by the motor to rotate, thereby driving the plate 3 to move below the ultrasonic welding head 21. When it moves below the ultrasonic welding head 21, the wire is placed on the plate 3, and then the ultrasonic welding head 21 is operated to move downward to weld the wire on the plate 3.

[0028] In this device, by setting the jig 14, when the plate 3 moves below the ultrasonic welding head 21, the plate 3 is located below the jig 14, that is, below the long bar 141, the first short bar 142, and the second short bar 143, and the welding space 145 just corresponds to the ultrasonic welding head 21, and the placement opening 144 is set for positioning, so that the operator can quickly place the wire on the plate 3, and one end of the wire can be located in the middle of the plate 3, thereby improving the welding quality;

[0029] After the ultrasonic welding head 21 completes welding, when the ultrasonic welding head 21 rises, due to some welding operations, the ultrasonic welding head 21 may stick to the wire and the plate 3. Therefore, the long bar 141, the first short bar 142, and the second short bar 143 are provided to limit the plate 3 when the ultrasonic welding head 21 rises, so as to prevent the plate 3 from rising together with the ultrasonic welding head 21.

[0030] In addition, when the ultrasonic welding head 21 rises, the plate 3 and the wire adhered to the ultrasonic welding head 21 will rise with the ultrasonic welding head 21, and then be blocked by the long bar 141, the first short bar 142, and the second short bar 143, and fall back to the first placement plate 121 and the second placement plate 131, so that when the first synchronous belt 113 and the second synchronous belt 114 rotate and bring the welded plate 3 and the wire to one side, the welded plate 3 and the wire can slide off the first placement plate 121 and the second placement plate 131 smoothly;

[0031] Therefore, the device can further assist the operator in performing ultrasonic welding on the wires and the plates 3 by means of the jig 14, thereby reducing operator fatigue, and can further improve the ultrasonic welding efficiency when the plates 3 are continuously placed on the first placement plate 121 and the second placement plate 131.

[0032] The second placement plate 131 is installed on the left side of the second bracket 13. When the operator places one end of the wire on the plate 3, it can avoid being blocked by the second bracket 13, further facilitating the operator to operate.

[0033] An alignment mark 146 is provided on the upper surface of the long rod 141 , and one end of the alignment mark 146 passes through a side of the long rod 141 close to the welding space 145 , so that an operator can quickly place the wire in the welding space 145 .

[0034] A guide plate 16 is installed at one end of the mounting frame 1 located at the first synchronous belt 113 and the second synchronous belt 114. The setting of the guide plate 16 can facilitate the guiding and sliding of the plate 3 and the wire that slide down from the first placement plate 121 and the second placement plate 131.

[0035] The mounting frame 1 is symmetrically fixedly connected with a slide rail 11, and a slide seat 111 is slidably connected to the slide rail 11. A connecting plate 112 is connected to the slide seat 111, and a locking bolt is threadedly connected to one side of the slide seat 111. By setting the slide rail 11 and the slide seat 111, the position of the connecting plate 112 relative to the ultrasonic welding head 21 can be easily changed, and the locking bolt can be easily locked after adjustment.

[0036] The utility model provides a jig 14 to further assist operators in performing ultrasonic welding on wires and plates 3, thereby reducing operator fatigue and improving work efficiency. Moreover, when plates 3 are continuously placed on the first placement plate 121 and the second placement plate 131, the ultrasonic welding efficiency can be further improved.
