Description

Technical Field

[0001] The invention relates to the field of automatic assembly of automobile door locks, in particular to automatic assembly equipment for PIN pins of automobile door locks. Background Art

[0002] The traditional method of inserting the pins of car door locks requires manual insertion of the pins into the corresponding positions on the door lock housing. This method is inefficient, time-consuming, and requires a lot of manpower costs. At the same time, manual operation is easily affected by subjective factors, making it difficult to ensure product quality and accuracy.

[0003] The Chinese invention patent application with publication number CN107363539A discloses "an automatic PIN insertion device", which includes a first insert PIN insertion mechanism, which includes a turntable supporting the first insert, a first insert conveying unit that carries the first insert to be inserted with a PIN from the turntable or carries the first insert with a completed PIN to the turntable, a translation unit that receives the first insert conveyed by the first insert conveying unit, a first PIN feeding unit, and a cam inserting machine that inserts the PIN on the first PIN feeding unit into the first insert to be inserted with a PIN; and a second insert PIN insertion mechanism, which includes a platform supporting the second insert, a second PIN feeding unit that conveys the second PIN to the platform, and a pin insertion unit that inserts the second PIN on the second PIN feeding unit into the second insert. It can efficiently and automatically insert the PIN into the insert of the car door lock, thereby saving labor costs.

[0004] The above patent application uses a cam pin insertion machine to insert the first PIN pin or the second PIN pin. However, since the first PIN pin or the second PIN pin is flat and slender, it is easy to deform during insertion, and the positioning accuracy is low, resulting in a low pin insertion qualification rate. In addition, only one PIN pin can be inserted at a time, and the automation efficiency is low. Summary of the invention

[0114] Step 1-2, PIN needle vibration loading: The first PIN needle or the second PIN needle located in the PIN needle storage box slides from the inclined slide plate to the PIN needle vibration tray at the bottom by vibration or other means, thereby realizing PIN needle vibration loading of the PIN needle vibration tray.

[0115] Step 1-3, PIN needle posture adjustment: The PIN needle vibration tray vibrates to adjust the PIN needle posture thereon.

[0116] Step 1-4, PIN needle posture detection: preferably use vision to detect the PIN needle posture on the PIN needle vibration tray, find the PIN needle that meets the set posture and record the position coordinates of the PIN needle on the PIN needle vibration tray.

[0117] In this embodiment, the PIN needle vibration material tray is a transparent plate, and a fill light is arranged under the transparent plate to facilitate visual detection.

[0118] Step 2, PIN needle feeding and grasping: The PIN needle feeding robot grasps the grasping part of the PIN needle that meets the set posture according to the position coordinates of the PIN needle that meets the set posture.

[0119] Step 3: PIN needle positioning, specifically including the following steps.

[0120] Step 3-1, PIN needle transfer tray reset: The PIN needle transfer tray is reset to the positioning position, and the side limit device of the transfer tray limits the PIN needle transfer tray.

[0121] Step 3-2, one-time inspection of tooling incoming materials: the tooling incoming material inspection device performs one-time inspection on whether there are PIN needles on the PIN needle positioning tooling.

[0122] Step 3-3, PIN needle positioning: When there is no PIN needle on the PIN needle positioning tooling, the PIN needle feeding robot rotates to the positioning station and places the grasped PIN needle that meets the set posture on the corresponding PIN needle positioning tooling; the PIN needle positioning tooling positions the placed PIN needle, wherein the vertical section of the PIN needle is in contact with the vertical side of the L-shaped transition section limit groove, and the pin is inserted into the pin positioning groove.

[0123] Step 3-4, secondary inspection of tooling incoming materials: The tooling incoming material inspection device performs secondary inspection on whether there are PIN needles on the PIN needle positioning tooling.

[0124] Step 3-5, PIN needle feeding: When it is detected that both PIN needle positioning tools on the same PIN needle transfer tray have PIN needles, the PIN needle transfer tray is transferred along the PIN needle feeding slide rail to the PIN needle loading station and waits for loading.

[0125] Step 4: feeding the door lock housing once, specifically comprising the following steps.

[0126] Step 4-1, one-time transmission of the door lock housing: the door lock housing line body transmits the door lock housing to the first PIN needle assembly station and blocks the limit position.

[0127] Step 4-2, the height of the door lock housing is raised: the lifting assembly located directly below the first PIN needle assembly station is started and lifted upward, so that the door lock housing rises to the set position along with the lifting plate.

[0128] Step 4-3, pressing the door lock housing: the pressing component located directly above the first PIN pin assembly station is lowered to press the top surface of the door lock housing away from the PIN pin hole.

[0129] Step 5: first PIN needle transfer and assembly, specifically including the following steps.

[0130] Step 5-1, the assembly jaws are moved to the PIN needle loading station: the PIN needle two-dimensional transfer plate in the PIN needle transfer assembly component in the first PIN needle assembly device slides to the PIN needle loading station under the action of the horizontal driving device.

[0131] Step 5-2, first PIN needle grabbing, specifically includes the following steps.

[0132] Step 5-2A, assembly jaws open: both the left assembly jaw and the right assembly jaw are opened outwards.

[0133] Step 5-2B, lowering the height of the assembly clamp: The PIN two-dimensional transfer plate is lowered under the action of the height lifting device, thereby driving the assembly clamp to lower its height until the assembly push plate extends into the L-shaped groove of the L-shaped transition section of the first PIN and is at a set gap distance from the horizontal section. At this time, the pin limit slot of the left assembly clamp is facing the side of the pin grabbing part.

[0134] Step 5-2C, move the left clamping jaw inward: Move the left clamping jaw inward by a specified distance so that the pin limiting slot clamps the pin from the side of the pin grabbing portion. At this time, the depth of the pin entering the pin limiting slot is preferably greater than half of the pin width.

[0135] Step 5-2D, the height of the assembly clamp is raised: the height of the assembly clamp is raised until the first PIN is disengaged from the PIN positioning tooling.

[0136] Step 5-2E, move the right clamping jaw inward: Move the right clamping jaw inward to completely clamp the grabbing portion of the first PIN into the pin limit slot in the width direction again, and form a clamping fit with the left clamping jaw.
