Abstract
Description
Technical Field
[0001] The utility model belongs to the related technical field of processing auxiliary appliances for electronic devices, and particularly relates to a PIN - foot pressing fixture. Background Technique
[0002] In electronic devices, for the control board of a motor remote controller (as shown in Figure 1 ), it mainly includes a PCB board, several surface - mounted components, and several electronic components plugged into the PCB board. The number of components plugged into the PCB board is relatively small, at most 10. Such electronic components generally have two PIN feet, which serve as the positive and negative electrodes respectively. After such electronic components are plugged into the corresponding plug - in holes on the circuit board, the corresponding PIN feet need to be welded, and then the redundant PIN feet are cut off. However, considering the small number of PIN feet on such motor remote controllers, currently, generally, electronic components are first plugged in manually and then put into an automatic soldering machine for automatic soldering to improve work efficiency.
[0003] However, there are the following problems when plugging in electronic components: Since the two PIN feet of such current electronic components with PIN feet are generally arranged in parallel, and in order to facilitate the insertion of the PIN feet into the corresponding soldering through - holes on the PCB board, the diameter of the PIN feet is relatively smaller than the diameter of the corresponding soldering through - holes on the PCB board. This can facilitate plugging and there will be no problem of jamming during plugging. However, once the component is inserted into the corresponding soldering through - hole on the PCB board, it is easy to be loose. Therefore, after plugging in one electronic component, the two PIN feet of this electronic component need to be shaped, that is, the two PIN feet are clamped by a handle and bent to both sides respectively to increase the distance between the two PIN feet (this step is also called PIN - foot shaping). This can ensure that when the electronic component is inserted into the PCB board, it will not be loose, facilitating subsequent automatic soldering. However, such an operation undoubtedly increases labor costs, and when operating manually, the force cannot be too large, otherwise it is easy to break the PIN feet, resulting in the scrapping of the component. Therefore, improvement is needed. Summary of the Utility Model

[0029] Embodiment 1
[0030] Please refer to Figure 2 - 10As shown in the figure, a PIN - foot pressing fixture disclosed in this embodiment includes a housing 1. The housing 1 includes an upper table surface 2. A gripper 3 is provided on the upper table surface 2. A positioning die 4 inserted from the front end of the gripper 3 is clamped by the gripper 3. A profiling cavity 401 for placing a motor remote - control board 28 is provided on the positioning die 4. A protective bracket 5 with an open front end is provided on the housing 1. A cylinder 6 is provided above the protective bracket 5. The piston rod of the cylinder 6 passes through the top of the protective bracket 5 and is connected to a lifting plate 7. A pressing - foot head fixing plate 8 is provided below the lifting plate 7. More than one profiling pressing foot head 9 is provided on the lower surface of the pressing - foot head fixing plate 8. The profiling pressing foot head 9 is used to push the two PIN - feet of the electronic component with PIN - feet above the motor remote - control board outwards. Slopes 901 are provided on both sides of the bottom of the profiling pressing foot head 9.
[0031] Preferably, in order to protect the lower motor remote - control board, pre - position the motor remote - control board, and protect the profiling pressing foot head 9 at the same time, four guide sleeves 10 distributed in the front - rear, left - right directions are provided below the lifting plate 7. The guide sleeves 10 penetrate through the pressing - foot head fixing plate 8. A first guide rod 11 that can move up and down is inserted into each guide sleeve 10. A pressing - foot head protection plate 12 is connected between the lower ends of the four first guide rods 11. A spring 13 is sleeved outside each first guide rod 11 extending out of the pressing - foot head. One end of the spring 13 abuts against the bottom surface of the pressing - foot head fixing plate 8, and the other end of the spring 13 abuts against the upper surface of the pressing - foot head protection plate 12. An avoidance groove through - hole 14 for the profiling pressing foot head 9 to penetrate is provided on the pressing - foot head protection plate 12.
[0032] Preferably, in order to achieve a guiding function, four flange bearings 15 distributed in the front - rear, left - right directions are provided on the lifting plate 7. A second guide rod 16 is inserted into each flange bearing 15. The upper end of the second guide rod 16 is connected to the top of the protective bracket 5, and the lower end of the second guide rod 16 is connected to the upper table surface 2. By setting the second guide rod 16, when the lifting plate 7 moves up and down, it can play a guiding role, avoiding position deviation during up - and - down movement, and ultimately affecting the inability of the lower profiling pressing foot head 9 to perform PIN - foot shaping operations.
[0033] Preferably, to improve the safety during operation, two gratings 17 distributed left - right are provided on the upper table surface 2. A controller 20 electrically connected to the gratings 17 and the cylinder 6 is provided inside the housing 1. In this embodiment, the function of setting the gratings 17 is that during the normal use of the device, if a hand approaches, the light emitted by the two gratings 17 is blocked by the hand, and a signal is immediately sent to the controller 20 for automatic emergency stop processing, thereby improving safety.
[0034] Preferably, for the convenience of installation, the protective bracket 5 is a frame structure with an operation entrance at the front, which is formed by splicing a left side plate 501, a right side plate 502, a rear baffle 503 and a top plate 504. The left side plate 501 and the right side plate 502 are arranged in parallel. An L-shaped connecting bracket 18 is arranged on the inner sides of the left side plate 501 and the right side plate 502. The bottom of the grating 17 is fixed on the upper table surface 2, and a fixing rod 19 is arranged at the upper end of the grating 17. The fixing rod 19 is fixed on the L-shaped connecting bracket 18. Through the above structural arrangement, the grating 17 is fixed to prevent it from moving.
[0035] Preferably, the outer shell 1 includes an upper shell 101 and a lower bottom plate 102. The controller 20 is fixed in the upper shell 101. A cylinder lifting button 21 and a cylinder emergency stop button 22 electrically connected to the controller 20 are arranged at the front end of the upper shell 101. A power switch 23 and a power supply plug 24 electrically connected to the controller 20 are arranged at the rear end of the upper shell 101. By setting the power switch 23, the whole device can be turned on or off. By setting the cylinder lifting button 21, the lifting operation of the cylinder can be realized. By setting the cylinder emergency stop button 22, the emergency stop operation of the cylinder can be realized. It should be noted that the specific models of the cylinder lifting button 21, the cylinder emergency stop button 22, the grating 17, the cylinder 6 and the controller 20, and how the controller 20 is connected to and controls the electronic components belong to the conventional technology in this field, so no specific description will be made here.
[0036] Preferably, for the convenience of later maintenance of the internal controller, the upper shell 101 and the lower bottom plate 102 are movably connected, and more than one hinge 25 is hinged between the back surface of the upper shell 101 and the lower bottom plate 102. The sides of the upper shell 101 and the lower bottom plate 102 are respectively provided with a lock structure 26. In this embodiment, the lock structure 26 is considered as an existing technology, so its specific structure belongs to the conventional technology in this field, and no detailed description will be made here. By arranging the hinge 25 between the back surface of the upper shell 101 and the back surface of the lower bottom plate 102, when the lock structure 26 is opened, the upper shell 101 can be opened to expose the internal controller 20.
[0037] Preferably, for the convenience of moving the whole device, handles 27 are hinged on both sides of the upper shell 101.
[0038] Since the distribution structure of the PIN pins 281 on the motor remote control board 28 is as Figure 1As shown, for some components, such as a relay having 4 PIN feet 281, and the four PIN feet 281 are distributed in the front, back, left, and right directions. The distances between the two PIN feet 281 distributed on the left and right of the relay and the two PIN feet on the electronic component having only two PIN feet are the same. Therefore, in order to further reduce components, such as Figure 8 As shown, the length L of the profiling presser foot head 9 needs to be greater than the distance between the two PIN feet on the electronic component having two PIN feet, and the thickness W of the profiling presser foot head 9 needs to ensure that one profiling presser foot head 9 can simultaneously shape the four PIN feet 281 of the relay, and when it is an electronic component having only two PIN feet, it can also press down to separate the distance between the two PIN feet, so as to reduce components;
[0039] The specific working principle of this structure is as follows: When it is necessary to shape the PIN feet 281, turn the side of the motor remote control board 28 where the PIN feet 281 are exposed upwards, place the motor remote control board 28 into the profiling cavity 401 for positioning, and then drive the device to work. The cylinder 6 works to drive the lifting plate 7 to move downwards, synchronously driving the presser foot head fixing plate 8 to move downwards. During the downward movement, let the presser foot head protection plate 12 first touch the motor remote control board 28 and press the motor remote control board 28 tightly. Then the cylinder 6 continues to work until the profiling presser foot head 9 continues to move downwards. The left and right sides of the profiling presser foot head 9 will push the corresponding left and right PIN feet 281 outwards to realize the shaping operation of the PIN feet, thereby changing the distance between the two PIN feet 281 of the same electronic component. In this way, it can be ensured that the electronic component will no longer move or fall out from the welding holes on the motor remote control board 28. Then the motor remote control board 28 is sent into the automatic welding equipment to realize automatic welding. Therefore, through the automatic shaping of the PIN feet 281 by the profiling presser foot head 9 on this fixture, and achieving it in one step, compared with manual operation, the working efficiency is higher, the labor cost is reduced, and the force is easier to control, and it is not easy to break the PIN feet. At the same time, by providing inclined surfaces 901 on both sides of the bottom of the profiling presser foot head 9, it is convenient to insert into the distance between the two PIN feet on both sides when pressing down.
[0040] It should be noted that in the later stage, the corresponding number of profiling presser foot heads 9 can be selected according to the distribution quantity of the PIN feet 281 on the final motor remote control board 28.
[0041] The above is only the preferred embodiment of the present invention and does not limit the present invention. Any modification to the technical solutions recorded in the foregoing embodiments, any equivalent replacement of some technical features, and any modification, equivalent replacement, and improvement made all fall within the protection scope of the present invention.
