Detailed Implementation

[0019] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are only preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the embodiments without creative effort are all within the protection scope of this utility model.

[0020] Please see Figure 1-4 A Z-axis locking system for a planar motion braking device of an automatic flipping machine includes a locking mechanism disposed on the placement head of the automatic flipping machine. The automatic placement machine is provided with a moving component that controls the movement of the placement head in the X-axis, Y-axis and Z-axis directions. The locking mechanism includes a lifting component disposed on the placement head via a mounting component, a control component disposed on the mounting component and controlling the lifting component to move vertically, a locking piece 12 disposed horizontally below the lifting component, and a locking block 13 disposed on the placement head and abutting against the bottom side of the locking piece 12.

[0021] like Figure 1-4As shown, the lifting component, which moves vertically a certain distance, is driven by the control component to move vertically. This facilitates the control of the distance between the lifting component and the locking piece 12, and makes it easy to adjust the lifting component to a suitable position to control the downward movement of the lifting component to lock the locking piece 12 on the locking block 13. The locking force can be adjusted conveniently and accurately, which improves the stability and efficiency of the automatic inversion machine in high-precision operation.

[0022] The mounting components include a fixing block 1 that is detachably mounted on the mounting head in the vertical direction, and a fixing seat 2 that is slidably disposed in an adjustment groove 17 on one side of the fixing block 1. The fixing seat 2 has an L-shaped structure, and a lifting component is disposed on the horizontal side of the adjusting groove 17. The control component is disposed on the fixing block 1 and controls the fixing seat 2 to move downward in the adjusting groove 17.

[0023] The side of the fixing block 1 away from the adjusting groove 17 has an adjusting hole 16 that communicates with the adjusting groove 17 in the vertical direction, and a fixing bolt that can be threaded to the fixing seat 2 passes through the adjusting hole 16.

[0024] like Figure 1-2 As shown, when the vertical side of the fixing seat 2 is inserted into the adjustment groove 17, two fixing bolts are respectively inserted into different adjustment holes 16 and threadedly connected to the fixing seat 2. This makes it easy to fix the position of the fixing seat 2 in the adjustment groove 17 when the ends of the fixing bolts are tightly attached to the bottom wall of the adjustment hole 16. The fixing seat 2 can also be moved in the vertical direction.

[0025] The adjustment assembly includes a connecting block 14 that is horizontally fixed on the fixing block 1 and located above the fixing seat 2, a pressure plate 3 that is horizontally installed on the top of the vertical side of the fixing seat 2 and located on the connecting block 14, and an adjustment screw 15 that is vertically set and threaded through the bottom of the pressure plate 3 and tightly fits against the top side of the pressure plate 3.

[0026] like Figure 1-3 As shown, the operator rotates the adjusting screw 15, and the adjusting screw 15 is threadedly connected to the connecting block 14, so that the bottom of the adjusting screw 15 moves downward away from the connecting block 14. At this time, the bottom end face of the pressure plate 3 is tightly attached to the fixed seat 2, which drives the fixed seat to move downward in the adjusting groove 17, so as to adjust the distance between the lifting assembly and the locking piece 12.

[0027] Adjusting screw 15 is a special screw that is galvanized. By forming a wear-resistant and friction-enhancing layer on the metal surface, the friction between the contact surfaces is increased.

[0028] The adjusting screw 15 is designed with a high-precision thread structure. The operator can precisely adjust the distance of the electromagnet 4 in the Z direction by rotating the adjusting screw 15. After adjustment, the clamping force between the locking plate 12 and the locking block 13 can be controlled within a preset range to ensure the stable positioning of the mounting head.

[0029] This application relates to the Z-axis motion module of the placement head on the automatic flip-chip machine;

[0030] During the placement operation, after the placement head moves to the predetermined position, the Z-axis braking device is triggered. The locking system adjusted by the adjusting screw 15 presses the locking plate 12 against the locking block, so that the placement head is completely fixed in the Z-axis, ensuring a high-quality connection at the placement point;

[0031] The clamping force of the Z-axis locking plate can be finely adjusted by adjusting screw 15, which can meet the requirements of high-precision flip mounting.

[0032] The adjustable adjustment screw 15 design allows the device to adapt to a variety of flip-board processes, meeting the needs of different workpieces and processes without the need to replace parts.

[0033] The high-strength structural design of the adjusting screw 15 and the fixing block 1 ensures the stability and durability of the locking device during long-term, high-frequency use.

[0034] Operators can adjust the movement distance and locking force simply by rotating the control screw 15, without the need for additional tools or complicated adjustments.

[0035] The lifting assembly includes a lifting member disposed on one side of the fixed base 2 in a horizontal orientation, a lifting rod 6 that passes through the fixed base 2 vertically and extends below the fixed base 2, a push column 9 disposed on the bottom end of the lifting rod 6 and located above the locking plate 12, and a limiting ring 8 that is movably sleeved on the side of the push column 9 and disposed on the fixed base 2. The lifting member controls the lifting movement of the lifting rod 6.

[0036] The lifting component includes an electromagnet 4 mounted on the top of the horizontally positioned side of the fixed base 2 and movably sleeved on the lifting rod 6; a lifting plate 7 mounted above the electromagnet 4 and fixedly mounted on the lifting rod 6; and a limiting spring 19 movably sleeved on the lifting rod 6 and fixedly connected at both ends to the lifting plate 7 and the bottom wall of the lifting hole 5, respectively. The top end face of the electromagnet 4 is sleeved on the lifting rod 6 and has a lifting hole 5. The lifting plate 7 is made of iron and has a fixing ring 18 on its bottom end face that is sleeved on the limiting spring 19 and passes through the lifting hole 5.

[0037] like Figure 1-4As shown, after the pressure plate 3 is moved downward in the vertical direction by rotating the adjusting screw 15, and after the mounting head has moved in the Z direction, the electromagnet 4 is energized. The electromagnet 4 generates magnetic force, which attracts the lifting plate 7, causing the lifting plate 7 to move towards the electromagnet 4 and compress the limiting spring 19 sleeved on the lifting rod 6. At this time, the lifting rod 6, which is fixedly connected to the lifting plate 7, synchronously drives the push column 9 to move downward to lock the locking piece 12 located on the locking block 13. After adjusting the distance by the adjusting screw 15, it is easy to ensure the locking force of the push column 9 on the locking piece 12. When it is necessary to control the mounting head to move in the Z direction, the energization of the electromagnet 4 is disconnected. When the limiting spring 19 returns from the compressed state, the lifting plate 7 and the lifting rod 6 are moved upward, which in turn drives the push column 9 set at the bottom of the lifting rod 6 to move upward.

[0038] When the limit spring 19 is in its normal extended state, the push post 9 is located above the locking plate 12.

[0039] The locking plate 12 is mounted on the placement head by a fixing member. The fixing member includes a mounting block 10 mounted on the placement head and its top side is fitted onto one side of the locking plate 12 through a mounting groove, a pressure block 11 mounted above the locking plate 12 and capable of clamping the locking plate 12, and a locking block 13 mounted directly below the push post 9 and its top side is in contact with the bottom side of the locking plate 12. The locking block 13 is mounted on the placement head.

[0040] The connecting block 14 on the fixing block 1 has a threaded hole for inserting the adjusting screw 15. The adjusting screw 15 can be rotated to adjust the clamping force between the locking plate 12 and the locking block 13.

[0041] The adjusting screw 15 is designed with a high-precision thread structure, allowing the operator to precisely adjust the Z-axis movement distance of the electromagnet 4 by rotating the adjusting screw 15.

[0042] The limiting ring 8 uses a Z-axis brass bushing. The Z-axis brass bushing can withstand high loads and high temperatures without deforming or wearing out too quickly, possessing good strength and hardness while maintaining ductility. It has good wear resistance and provides excellent corrosion resistance.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
