Description

Technical Field

[0001] This utility model relates to the field of bit selectors, and more particularly to a foolproof bit selector. Background Technology

[0002] Screw tightening is a very common and critical operation. As an essential tool for tightening screws, the correct selection and use of screwdriver bits plays a vital role in ensuring product quality and improving production efficiency. Different sizes and types of screws require corresponding screwdriver bits; choosing the wrong bit can lead to a series of problems such as incomplete tightening, stripped threads, and product damage.

[0003] A foolproof bit selector is a tool used in automated production or assembly operations to help operators accurately select the correct bit, prevent misuse, and improve work efficiency and quality. Foolproof bit selectors on the market employ various foolproof designs to assist operators in correctly selecting bits. Among these, the shape-matching slot design is a common approach. This design uses slots on the bit holder that match the shapes of different bits, ensuring that only bits of a specific shape can be placed in the corresponding slot.

[0004] Existing foolproof bit selectors generally lack the function of detecting bit weight. Bit weight is an important physical attribute, and bits of different specifications and materials often have different weights. Current foolproof bit selectors cannot further improve the accuracy and reliability of foolproofing through weight detection. Utility Model Content

[0024] The present invention will be further described below with reference to specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of protection of the present invention.

[0025] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0026] Reference Figures 1-4 A foolproof bit selector includes: a bit holder 100; a bit detection rod 300 installed in the bit holder 100 for holding bits; and a weighing sensor 302 installed on the bit detection rod 300 for detecting the weight of the bits.

[0027] In this embodiment, a weighing sensor 302 is installed on each bit detection rod 300 to detect the weight of the bit. When a bit is removed or placed in, the weighing sensor 302 detects the weight change and compares it with the preset standard weight of that bit. If the weight does not meet the standard (e.g., the wrong bit is placed), the control system will issue an alarm to remind the operator to check if the bit is correct.

[0028] The bit holder 100 includes: a placement slot 101 formed on the bit holder 100, and the bit detection rod 300 installed in the placement slot 101; the number of placement slots 101 is at least two.

[0029] The bit detection rod 300 includes: a docking groove 301, which is formed at the top of the bit detection rod 300, and the bit is disposed in the docking groove 301. The weighing sensor 302 is installed on the bottom wall of the docking groove 301.

[0030] The bit holder 100 further includes: a control box 200, installed at the bottom of the bit holder 100; a first power source 201, installed inside the control box 200; and a lead screw 202, one end of which is threadedly connected to the bit detection rod 300, and the other end of which passes through the bottom wall of the placement groove 101 and is connected to the power shaft of the first power source 201.

[0031] One end of the aforementioned lead screw 202 is threadedly connected to the bit detection rod 300, and the other end passes through the bottom wall of the placement slot 101 and is connected to the power shaft of the first power source 201. When the first power source 201 drives the lead screw 202 to rotate, the lead screw 202 will drive the bit detection rod 300 to move up and down linearly within the placement slot 101, realizing the extension and retraction of the bit. The operator selects the desired bit by pressing the button 103. After receiving the signal, the control box 200 drives the first power source 201 to rotate, and the lead screw 202 drives the bit detection rod 300 to rise, pushing the bit out of the placement slot 101 for easy retrieval by the operator. After use, the operator puts the bit back into the docking slot 301, and the first power source 201 drives the lead screw 202 to lower the bit detection rod 300, retracting the bit into the placement slot 101.

[0032] The bit holder 100 further includes: a locking lever 400, installed on the top of the bit holder 100, for locking the placement slot 101; a second power source 401, installed on the bit holder 100, the power shaft of the second power source 401 being connected to the locking lever 400; an indicator light 102, installed on the top of the bit holder 100; and a button 103, installed on the top of the bit holder 100.

[0033] The locking lever 400 is used to lock the slots 101, preventing the bits from being accidentally removed when not in use. When a bit is selected, pressing button 103 unlocks the corresponding slot 101, while the other slots 101 automatically lock, preventing the bit from being removed. The other slots 101 will only unlock after the bit is used and returned, effectively preventing confusion caused by removing multiple bits simultaneously. Indicator light 102 is installed on the top of the bit holder 100 and uses a high-brightness LED, offering advantages such as high luminous intensity and long lifespan. The color of indicator light 102 can be set according to actual needs; for example, green indicates that the bit in the slot 101 is usable, while red indicates that the bit in the slot 101 is faulty or occupied. Button 103 is installed on the top of the bit holder 100 and is made of a tactile material for easy pressing by the operator. Button 103 is used to trigger various operations of the selector, such as selecting a bit and unlocking the locking lever 400.

[0034] During use, each bit detection rod 300 is in the initial lowered position in the multiple placement slots 101 on the bit holder 100. The bit is placed in the docking slot 301 at the top of the bit detection rod 300. The locking rod 400 is in the state of locking all placement slots 101. The indicator light 102 shows the initial state. Normally, the indicator light 102 corresponding to the unused placement slot 101 is green, indicating that the bit can be used normally. According to the work requirements, the operator finds the button 103 of the corresponding bit on the top of the bit holder 100 and presses it.

[0035] When button 103 is pressed, a signal is transmitted to control box 200. After receiving the signal from button 103, control box 200 starts the first power source 201 inside control box 200. The first power source 201 drives the lead screw 202 connected to its power shaft to rotate. Since one end of the lead screw 202 is threadedly connected to the bit detection rod 300, the rotation of the lead screw 202 drives the bit detection rod 300 to make an upward linear motion in the placement slot 101. The bit detection rod 300 rises and pushes the bit out of the placement slot 101 for easy access by the operator.

[0036] Simultaneously, the control box 200 activates the second power source 401, driving the locking lever 400 to unlock only the slot 101 containing the selected bit, while keeping the other slots 101 locked to prevent accidental removal of other bits. After use, the operator places the bit back into the docking slot 301 at the top of the bit detection lever 300. This return action triggers the control box 200, which then activates the first power source 201 again, causing it to rotate in the reverse direction. The first power source 201 drives the lead screw 202 to rotate in the reverse direction, thus re-activating the bit detection lever 300. Under the action of the lead screw 202, the bit moves downward in a straight line along the placement slot 101 until it returns to the initial position. The bit is retracted into the placement slot 101. The control box 200 detects that the bit has been returned to its position and restarts the second power source 401, causing the locking lever 400 to relock the placement slot 101. At the same time, the control box 200 controls the status update of the indicator lights 102 corresponding to all placement slots 101. The indicator lights 102 of unused placement slots 101 return to green. If a bit is being used, the corresponding indicator light 102 remains in another state (such as yellow).

[0037] During the process of removing or placing the bit into the docking slot 301, a weighing sensor 302 installed on the bottom wall of the docking slot 301 detects weight changes in real time. The weighing sensor 302 transmits the detected weight data to the control box 200. The control box 200 compares this data with the preset standard weight of the bit. If the weight does not meet the standard, for example, if the wrong bit is placed, the control system immediately issues an alarm. The alarm can be triggered by a buzzer connected to the control box 200, and simultaneously, the indicator light 102 on the top of the bit holder 100 corresponding to the placement slot 101 turns red, reminding the operator to check if the bit is correct. The operator must promptly correct the error and reselect or place the correct bit.

[0038] In summary, compared with existing technologies, it has the following beneficial effects:

[0039] By installing a load cell 302 on the bottom wall of the docking groove 301, the weight of the screwdriver bit is detected in real time and compared with a preset standard. Screwdriver bits of different specifications and materials have different weights. Utilizing this characteristic, an alarm is triggered if the weight does not match, greatly improving the accuracy of error prevention.

[0040] The first power source 201 drives the lead screw 202 to raise the bit detection rod 300 to push out the bit, making it easy to pick up and put back after use. The control box 200 automatically controls the bit detection rod 300 to lower and retract the bit. The second power source 401 controls the locking rod 400 to unlock only the selected bit placement slot 101 to prevent multiple bits from being taken and confused. The picking and returning process is clear and orderly, improving work efficiency.
