[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Embodiment: An automatic assembly device for automobile door locks, such as Figure 1-Figure 4As shown, it includes a base 1, a stamping arm 2 fixedly mounted on the base 1 and a stamping assembly 3 fixedly mounted on the stamping arm 2. A fixed disk 4 is fixedly mounted on the top face of the base 1 corresponding to the output part of the stamping assembly 3. When in use, the locking plate of the automobile door lock is placed on the fixed disk 4, and the stamping assembly 3 is started to perform stamping processing on the locking plate of the automobile door lock. In this embodiment, a switch 5 for controlling the opening of the stamping assembly 3 is fixedly mounted on the right side of the front end of the base 1, and a loading tray 6 for placing workpieces to be processed is provided on the left side of the front end of the base 1. A touch sensor is also provided at the bottom of the loading tray 6, and the touch sensor is connected in series with the switch 5. When in use, the switch 5 can only be pressed to open after the touch sensor on the loading tray 6 detects a human hand touch, thereby starting the stamping assembly 3. In this way, when in use, it can be ensured that the hands of the operating workers will not be located under the stamping assembly 3, which greatly improves the safety of the processing.

[0027] Furthermore, in order to improve the degree of automation, two groups of connecting pillars 7 are fixedly installed on one side of the fixed plate 4. The connecting pillars 7 are rectangular blocks. A rotating rod 8 that can rotate around its own axis is movably installed between the two groups of connecting pillars 7. The rotating rod 8 is a long round rod. A workpiece tray 9 is integrally formed on the wall of one side of the rotating rod 8. The workpiece tray 9 is a rectangular plate that can carry the workpiece. A flip spring 19 is provided at the end of the workpiece tray 9 away from the connecting pillar 7. The elastic force of the flip spring 19 can bounce the workpiece tray 9 up, driving the workpiece on the workpiece tray 9 to slide out of the workpiece tray 9. A locking device is fixedly installed on the other side of the fixed plate 4 corresponding to the connecting pillar 7. The locking device can keep the workpiece tray 9 in a horizontal state. When the workpiece is placed on the workpiece tray 9 and stamped, the locking device is closed to release the workpiece tray 9, so that the workpiece tray 9 bounces up under the elastic force of the flip spring 19 and the workpiece is discharged.

[0028] In some embodiments, the locking device includes a lock hook seat 10 fixedly mounted on a fixed disk 4, a connecting rod 11 is horizontally movably mounted in the lock hook seat 10, the connecting rod 11 is a long round rod, a clamping rod 12 is fixedly mounted on the side wall of the connecting rod 11, an upper pressure plate 13 is integrally formed at one end of the clamping rod 12 close to the workpiece pallet 9, the upper pressure plate 13 is a triangular block with a horizontal bottom, which can lock the workpiece pallet 9, and by rotating the connecting rod 11, the clamping rod 12 and the upper pressure plate 13 are driven away from the workpiece pallet 9, thereby unlocking the workpiece pallet 9, and at the same time, the inclined surface on the top of the upper pressure plate 13 starts the guiding function when re-locking the workpiece pallet 9.

[0029] In other embodiments, the connecting pillar 7 can slide up and down along its own axis on the fixed plate 4, and the side wall surface of the connecting pillar 7 is sleeved with a return spring 18. During stamping, the elastic buffer provided by the return spring 18 and the flip spring 19 can reduce the rigid impact when the stamping just contacts, thereby reducing damage to the processed products.

[0030] In order to further increase the degree of automation of the assembly equipment, on the basis of the above embodiment, the clamping rod 12 is integrally formed with a lower support plate 14 at a position corresponding to the position below the upper pressure plate 13, and the upper surface of the lower support plate 14 is an arc-shaped surface. When locked, the workpiece pallet 9 is located between the upper pressure plate 13 and the lower support plate 14, and the lock hook seat 10 is fixedly installed with a deviation block 15 at a position corresponding to the position below the lower support plate 14. The deviation block 15 can be inserted into the gap below the lower support plate 14. Furthermore, a spring ring 16 is fixedly installed at the middle part of the connecting rod 11, and a locking spring 17 is sleeved on the connecting rod 11 at a position corresponding to the spring ring 16 and the locking hook seat 10. The locking spring 17 is an elastic spring, which enables the connecting rod 11 to always maintain a tendency to move forward. The card rod 12 is in a locked state, and the deviation block 15 overlaps with the card rod 12. Under the action of the elastic force of the locking spring 17, the front of the card rod 12 fits with the deviation block 15. When punching, the workpiece pallet 9 slides down as a whole to press the lower support plate 14, and the lower support plate 14 is used to drive the connecting rod 11 to deflect, thereby pushing the card rod 12 away to the side of the deviation block 15. At this time, under the action of the elastic force of the locking spring 17, the connecting rod 11 moves forward, and the deviation block 15 is inserted into the gap under the lower support plate 14, blocking the card rod 12 from approaching the workpiece pallet 9. When the punching head is restored, the workpiece pallet 9 ejects the workpiece under the action of the elastic force of the flip spring 19, automatically unlocks and detaches from the workpiece, and improves the degree of automation.

[0031] Furthermore, a workpiece slot 20 for accommodating a workpiece is provided in the middle of the workpiece tray 9 , and a workpiece guide slot 21 with an outer edge expanding outward is provided on the top surface of the workpiece slot 20 , thereby facilitating the workpiece to slide into the workpiece slot 20 .

[0032] The working principle of the utility model is as follows: when in use, the switch 5 can only be pressed and turned on after the touch sensor of the loading tray 6 detects the touch of a human hand, thereby starting the stamping assembly 3. In this way, when in use, it can ensure that the hands of the operating worker will not be located under the stamping assembly 3, greatly improving the safety of the processing.

[0033] Place the workpiece on the workpiece pallet 9, and quickly slide the workpiece into the workpiece slot 20 through the outward-expanded workpiece guide slot 21. Press the workpiece pallet 9 to slide one side of the workpiece pallet 9 between the upper pressure plate 13 and the lower support plate 14. Push the connecting rod 11 backward and rotate the connecting rod 11 to rotate the upper pressure plate 13 to the top of the workpiece pallet 9, and the lower support plate 14 to the bottom of the workpiece pallet 9. At this time, one hand is placed on the loading tray 6, and the other hand presses the switch 5 to start the stamping assembly 3 to stamp the workpiece on the workpiece pallet 9. During stamping, the return spring 18 and the flip spring 19 are released. The performance is able to buffer rigid impact and reduce damage to the workpiece. During buffering, the workpiece pallet 9 presses down the support plate 14 to deflect the connecting rod 11, and then the clamping rod 12 rotates to the side of the deviation block 15. At this time, the connecting rod 11 moves forward under the action of the elastic force of the locking spring 17, and the deviation block 15 is inserted into the gap between the clamping rod 12 and the workpiece pallet 9 to prevent the clamping rod 12 from approaching the workpiece pallet 9. When the stamping is completed, the workpiece pallet 9 is automatically unlocked and popped up under the action of the elastic force of the flip spring 19, and the stamped workpiece is ejected, thereby improving the degree of automation.
