The utility model uses two sets of clamps to fix and convey the electrode head 1b with the lead wire 1a, namely, the electrode head 1b is loaded by the first clamp 3, the lead wire 1a is loaded by the second clamp 4, so that the electrode head 1b and the lead wire 1a can be smoothly assembled and conveyed and positioned on the main conveying device 2. During blanking, the main conveying device 2 conveys the first clamp 3 and the second clamp 4 for loading the electrode head 1b and the lead wire 1a, then the first clamp 3 and the second clamp 4 are opened by the material taking and discharging device 5 (described in detail later), the lead wire 1a and the electrode head 1b are taken away and put into the electrode head frame, and finally the first clamp 3 is reflowed by the first reflow device 6, the second clamp 4 is reflowed by the second reflow device 7, and the materials are reflowed to the rear material loading station, so that the first clamp 3 and the second clamp 4 are reused. Therefore, the automatic blanking device can realize the automation of the whole blanking process, and has high speed and high efficiency.

In a more specific embodiment of the present utility model, as shown in fig. 3, the main conveying device 2 includes a first rail groove 21 fixed on the frame 1 and capable of being mutually matched with the first clamp 3, a second rail groove 22 fixed on the frame 1 and capable of being mutually matched with the second clamp 4, and a conveying driving device 23; the conveying driving device 23 includes a conveying driver 231, a transmission rod 232 (where sliding connection means that a sliding pair for connecting the transmission rod 232 and the frame 1 is disposed between the transmission rod 232 and the frame 1) is disposed at an output end of the conveying driver 231, the first track groove 21, the second track groove 22 and the transmission rod 232 are all disposed along a front-rear direction, and a plurality of pushing block assemblies 233 capable of pushing the first clamp 3 or the second clamp 4 forward are disposed on the transmission rod 232 at intervals. The push block assembly 233 can push the first clamp 3 or the second clamp 4 forward only in one direction (fig. 3 shows one embodiment in which the transmission rod 232 is located below the second clamp 4, so that the push block assembly 233 pushes the second clamp 4).

Preferably, the conveying driver 231 is a linear driver such as a cylinder.

As described above, the conveying driver 231 intermittently drives the transmission rod 232 to advance and retract, and the pushing block assembly 233 can push the second clamp 4 forward only in one direction, so that the conveying driver 231 can convey the first clamp 3 and the second clamp 4 forward with a gap. In addition, after each advance, the positions where the first clamp 3 and the second clamp 4 stay are predictable, and a positioning device is not needed, so that the mechanism is simplified, and the cost is reduced.

This achieves the function that the push block assembly 233 can push the first clamp 3 or the second clamp 4 forward only in one direction.

Further, a certain friction force exists between the first clamp 3 and the first track groove 21 or between the second clamp 4 and the second track groove 22, and the friction force can ensure that the first clamp 3 and the second clamp 4 are not driven to retract when the push block assembly 233 is retracted.

When the first catch 32 unlocks the clamp cover 31, the clamp cover 31 is automatically opened. The second clamp 4 is provided with a second buckle 41 for opening and closing the second clamp 4, and one end of the second buckle 41 is pressed downwards to open the second clamp 4. As described above, to open the first clamp 3 and the second clamp 4, the first buckle 32 and the second buckle 41 need only be pushed down respectively.

As described above, in the blanking process, the cover opening device 51 opens the clamp cover 31 first; the ejection device 52 ejects the electrode head 1b out of the first fixture 3; then the two-axis translation module 53 is started to drive the material taking clamping assembly 54 and the jacking device 55 to be in place; then the jacking device 55 firstly opens the second clamp 4, and the material taking clamping assembly 54 can take out the electrode head 1b and the lead wire 1a; the last two-axis translation module 53 is activated again so that the take out clamping assembly 54 transfers the electrode head 1b and lead wire 1a into the electrode head frame.

In a more specific embodiment of the present utility model, as shown in fig. 9 and 10, the material clamping assembly 54 includes a plurality of first material clamping jaws 541 for clamping the lead wire 1a at the first clamp 3, a first material clamping driver 542 for driving the first material clamping jaws 541 to open and close, a second material clamping jaw 543 for clamping the lead wire 1a at the second clamp 4, and a second material clamping driver 544 for driving the second material clamping jaws 543 to open and close.

drivers

542, 544 are preferably jaw cylinders. The first material taking clamping jaw 541 is provided with a plurality of pairs, and mainly clamps the lead wire 1a which is close to the electrode head 1 b; the second material taking jaws 543 have only one pair, and are mainly used for clamping the trunk of the lead wire 1 a.

The vacuum chuck assembly 56 in the present utility model is mainly used for sucking the grasping electrode head 1b. This is due to: even if the lead wire 1a and the electrode tip 1b are not welded (the lead wire 1a and the electrode tip 1b are not connected, if only the lead wire 1a is grabbed, the electrode tip 1b may not be grabbed), the electrode tip 1b needs to be taken out, and only the lead wire 1a is grabbed by the material taking clamping assembly 54, so that the electrode tip 1b needs to be grabbed directly by the vacuum chuck assembly 56, and the situation that defective products cannot be taken out is avoided.

It should be noted that, the above-mentioned comprehensive use of the first material taking clamping jaw 541, the second material taking clamping jaw 543 and the vacuum chuck assembly 56 is that the lead wire 1a and the electrode tip 1b are respectively installed at the first fixture 3 and the second fixture 4, and multiple grabbing mechanisms are used for grabbing simultaneously, so that the material taking success rate is high, and defective products caused by pulling the lead wire 1a and the electrode tip 1b are avoided.

The jacking device 55 is mainly used for opening the second clamp 4, and the process is that the output end of the two-axis translation module 53 drives the jacking device 55 to descend (the material taking clamping assembly 54 also descends synchronously); during the descent, the limit plunger 552 first contacts the second clamp 4; when the jacking device 55 continues to descend, the limiting ejector rod 552 is jacked on the clamp 4 and gradually compresses the buffer spring 553 upwards; then, the pressing block 551 gradually contacts the second buckle 41 and presses one end of the second buckle 41, so that the second buckle 41 is opened, at this time, the second clamp 4 is opened, and the first material taking clamping jaw 541 and the second material taking clamping jaw 543 of the material taking clamping assembly 54 can start to clamp the lead wire 1 a. In the process of lifting the first material taking clamping jaw 541 and the second material taking clamping jaw 543, the limit ejector rod 552 does not lift immediately, but still keeps pressing on the second clamp 4 under the action of the buffer spring 553, so as to avoid the second clamp 4 being brought up.
