Background
The product is transferred from station to station, and a hanging fixture may be used. The suspension type clamp is moved to the upper part of the product, the clamp descends, clamps the product and ascends. The suspended clamp is then translated over another station, the clamp lowered, and the product placed on the station. For small-size products, the clamp comprises a left clamping jaw and a right clamping jaw, and the clamp can clamp the products by adopting the left clamping jaw and the right clamping jaw and displace the products.
The process of clamping the product by the two clamping jaws comprises that the two clamping jaws in an open state are positioned at the left side and the right side of the product, the two clamping jaws are folded under the driving of the same driving unit, and the two clamping jaws are simultaneously close to the product and clamp the product. In this process, the distances between the two jaws in the open state and the corresponding side walls of the product are not necessarily equal, and the possibility of the two being equal is extremely small, but the speeds at which the two jaws are driven by the drive unit are equal, so that there is a problem that one jaw has been in contact with the corresponding side walls of the product and the other jaw has not been in contact with the corresponding side walls of the product.
If the weight of the product is large, the clamping jaw which is in contact with the product is difficult to push the product to displace, the driving unit still acts, the pressure born by the clamping jaw is increased, the pressure sensor senses that the pressure reaches a preset value, a signal is fed back to the main control unit, the main control unit judges that the clamping jaw clamps the product, the driving unit is controlled to stop, but the other clamping jaw is not in contact with the product, and thus, the problem that the two clamping jaws do not clamp the product exists. Alternatively, the drive unit continues to operate until the other jaw is not in contact with the product, but since one jaw is already stationary, the drive unit is stuck by the jaw, causing the other jaw to also stop operating, and thus, there is still a problem in that both jaws cannot clamp the product.
