Description

Technical Field

[0001] The present invention relates to an assembly method and equipment, in particular to a method and equipment for automatically assembling PIN needles, belonging to the technical field of electrical automation. Background Art

[0002] Currently, PIN pins are used in various types of equipment such as instruments and meters for positioning and conductivity. Conventional PIN pin assembly is performed manually by plugging and pressing, which is inefficient. Especially for some scenarios where the PIN needs to be bent during the assembly process, the manual method is not only inefficient, but also due to manual errors of the operator, the assembly consistency is poor, resulting in unsatisfactory assembly results. Therefore, an automated equipment is urgently needed to solve the above problems. Summary of the Invention

[0003] The purpose of the present invention is to overcome the above-mentioned shortcomings and provide a PIN pin assembly method and equipment that realizes PIN pin assembly in an automated manner, thereby greatly improving the assembly efficiency of the PIN pin.

[0004] The object of the present invention is achieved like this:

[0005] A PIN needle assembly method, the method steps are:

[0006] Step 1: The feeding mechanism feeds the PIN pin onto the upper surface of the product to be assembled;

[0007] Step 2: The push block 1 located above the left end of the PIN pin presses the PIN pin downward under the action of the power mechanism to tilt the PIN pin;

[0008] Step 3: Push block 2 facing the right end of the PIN pin pushes the PIN pin along the length direction of the PIN pin under the push of the power mechanism, so that the left end of the PIN pin is inserted into the socket of the product to be assembled;

[0009] Step 4: Pushing block 3, under the push of the power mechanism, contacts the right end of the PIN needle in a direction perpendicular to the length of the PIN needle and continues to move forward, causing the PIN needle to bend;

[0010] Step 5: Push block 4 downwards to press the PIN into the PIN installation slot under the push of the power mechanism.

[0011] Preferably, the power mechanism is an air cylinder, an oil cylinder or a linear electric mechanism (such as an electric push rod or a screw nut module driven by a motor, etc.).

[0012] Preferably, the bottom surface of the push block 1 in step 2 is an inclined surface.

[0013] A PIN pin assembly device includes push blocks 1, 2, 3 and 4, which are driven by four power mechanisms respectively. Push blocks 1 and 4 are located above a product to be assembled, and the product to be assembled is fixedly arranged on a work table (specifically, a positioning mold can be installed on the work table to position and fix the product to be assembled to prevent it from being displaced during the subsequent PIN pin assembly process and affecting the assembly efficiency and effect). Push blocks 1 and 4 are driven by the power mechanism to perform lifting movements. Push block 2 is located above the left side of the product to be assembled and is driven by the power mechanism to move left and right. Push block 3 is located above the front end of the product to be assembled and is driven by the power mechanism to move back and forth.

[0014] Preferably, push block two is installed on the lower support frame, push block one and push block four are installed on the upper support frame, the lower support frame and the upper support frame are both installed on the bracket, and push block three is installed on the bracket or the workbench.

[0015] Preferably, the bottom surface of the push block 1 is an inclined surface.

[0016] Preferably, the forward path of the push block two is located below the positioning guide block and the push block one, and the forward path of the push block three is located below the positioning guide block and the push block four.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The present invention realizes the guiding, pushing, jacking, bending and slotting operations of the PIN pin through four pushing blocks (pushing block 1, pushing block 2, pushing block 3 and pushing block 4) driven by a power mechanism such as a cylinder. The entire process is fully mechanized and automated, thereby greatly improving the efficiency of the assembly operation compared with the manual method. The mechanized operation method is more consistent than the manual method, especially for the bending operation, the mechanical method is more unified, ensuring the assembly effect.

[0031] See also Figures 1 to 6 The present invention relates to a PIN pin assembly device, which includes a feeding mechanism 1 for providing PIN pins, and a front-placed vibrating feeding plate (the vibrating feeding plate is a conventional mechanism, and the drawings in the specification do not illustrate its entirety, only its discharge section) as the feeding mechanism 1 to input the PIN pins. At this time, the PIN pins are introduced along the positioning guide block 2, and the positioning guide block 2 with an inverted "L"-shaped structure is fixed on the lower support frame 201. After the PIN pin is in place, the middle part rests on the middle protrusion of the product to be assembled 401, and then the push block 1 3 is pressed down. The bottom of the push block 1 3 is an inclined surface, so that when the push block 1 3 presses the left end of the PIN pin, the PIN pin is pressed obliquely, that is, the right end of the PIN pin is tilted; at this time, the push block 2 4 is pushed to the left by pneumatic force to contact the PIN pin, so that the left end of the downwardly tilted PIN pin is guided by the inclined surface of the bottom of the push block 1 3, so that the left end of the PIN pin is inserted into the A point socket on the product to be assembled 401.

[0032] Subsequently, the push block 3 5 is pushed forward by the action of the cylinder, contacts the PIN needle from the side, and then continues to bend the PIN needle forward, and pushes the bent part to the top of the PIN needle installation groove 301. At this time, the push block 4 6 presses the PIN needle downward into the PIN needle installation groove 301 under the action of pneumatic force, thereby completing the assembly of the PIN needle.

[0033] In addition: It should be noted that the above specific implementation is only an optimization scheme of this patent. Any changes or improvements made by technicians in this field based on the above concept are within the scope of protection of this patent.
