Concrete, as shown in Figure 3, in the utility model above-described embodiment, described bolt 5 comprises one end with externally threaded screw rod 51 and the head construction 52 of the other end being fixed on described screw rod 51;
The external screw thread of described screw rod 51 coordinates with described nut 6 size regulating described accommodation space.
In the utility model above-described embodiment, bolt 5 adopts only has one end can the bolt of mounting nuts 6, the setting of this bolt 5 can not have the side board of the pallet-like of nut side as adjustment benchmark, can ensure that each block circuit board is all fixed on the same position of this auxiliary mould, reduce position deviation.Meanwhile, in embody rule of the present utility model, at least need the bolt that two identical, by 4 points of two positions, circuit board is fixed, circuit board is firmly placed in above-mentioned accommodation space.
Preferably, in the utility model embodiment, can be changed the size of accommodation space by the degree of tightness of adjusting nut, make this auxiliary mould can be applicable to the circuit board of different size, the scope of application is wide.
Further, in the utility model above-described embodiment, the shape of described screw rod 51 is cylinder, and the overall diameter of described screw rod 51 is less than the thickness of described first pallet-like 1, and the overall diameter of described screw rod 51 is less than the thickness of described second pallet-like 2; And the length of described screw rod 51 is greater than the width of described first pallet-like 1 and the width sum of described second pallet-like 2.
Concrete, the length of this screw rod 51 can determine the size of the circuit board that auxiliary mould of the present utility model can be placed, and the length of screw rod 5 is longer under normal circumstances, and the circuit board that can place is larger; But the length of this screw rod 51 is also relevant with factors such as the width of pallet-like, the hardness of screw rod itself, is not specifically limited at this to this length.
Concrete, in the utility model above-described embodiment, as shown in Figure 4, the shape of described first pallet-like 1 and the shape of described second pallet-like 2 are rectangular configuration.
In the utility model embodiment, this auxiliary mould apparent size requires strict, and horizontal sides must be vertical with side, and both sides angle in 90 °, namely pallet-like is rectangular configuration.The holder of this frock of utility can carry circuit board and enter chip mounter guide rail when carrying out location, limit like this, the side of frock and chip mounter guide rail are perfect fits.
In the utility model above-described embodiment, described first pallet-like 1 material and described second pallet-like 2 material are metal material.
Concrete, auxiliary mould of the present utility model adopts metal tray to replace the common pallet of traditional resin material, has lightweight feature, and can be implemented in its internal openings to install bolt; Preferably, described metal material is aluminium type material.
It should be noted that, aluminium type material is only better utility model of the present utility model, and be not used in the protection range of restriction the application, the metal material that such as copper, iron etc. are firm is all applicable in the utility model embodiment.
Further, the equal and opposite in direction of described first pallet-like 1 and described second pallet-like 2.
It should be noted that, the size of the first pallet-like 1 and the second pallet 2 is arranged to equal, contribute to batch production, improve working (machining) efficiency.And circuit board is carried the metal support pan arrest of lining completely by two panels, side plate washer regulates in conjunction with nut and fixedly positioning on this auxiliary mould by circuit board, the frock carrying circuit board is ask to carry out paster by putting into after the good chip mounter guide rail width of frock width adjusting, can position deviation be eliminated, realize High-efficient Production.
The application scenarios of auxiliary mould of the present utility model is specifically described below in conjunction with Fig. 2:
First the two panels metal tray of this frock is interconnected by two bolts and nut; Overall dimension precision is not high or erose circuit board is placed in this frock metal tray again; Then according to circuit board size adjustment nut, ensure that circuit board is held firmly in place in the metal tray of frock; Again according to the width adjustment chip mounter guide rail width of frock, also can be advisable by smooth and easy forward slip can ensure that frock both sides can ride in guide rail groove; And then circuit board conveying frock holder to be carried specifies station to start programming to chip mounter; Finally start paster according to the program of having debugged.
In whole paster process, it is inaccurate that the circuit board using the holder of this frock to carry will cause chip mounter to locate because of overall dimension deviation, can not find Mark point and frequent shutdown adjusts; Also can not because of dimensional discrepancy board falling or stuck on chip mounter guide rail.Therefore, the circuit board paster technique auxiliary mould that the utility model embodiment provides reduces the required precision to processing circuit board apparent size, reduces production cost, improves production efficiency, also substantially increases the quality of paster.
The above is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from principle described in the utility model; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
